Neuro

Neuro

An MVC framework that leverages MooTools.

Version: 0.2.6

Influences:

• Backbone
• Shipyard

Dependencies:

• MooTools-Core 1.x
• Is.js

Focus:

• leverage MooTools-Core
• provide base for applications
• provide a clean/clear API

Extensions:

• Neuro-Sync - Extends Neuro with a CRUD API
• Neuro-Company - Extends Neuro with an Observer API

Installation

Neuro is written as a CommonJS module and is available as an NPM package.

Node.js + NPM

---

Install Node.js + NPM and run the following command to install Neuro:

$ npm install Neuro

Afterwards, all you need to do to use Neuro is the following line in your scripts:

var Neuro = require('Neuro');

Script Tags

---

There are pre-built scripts of Neuro at your disposal as well. All you need is the following code to load:

<script type="text/javascript" src="/path/to/neuro.js"></script>

Choose between two files:

• neuro.js - Packaged with WrapUp which exposes the Neuro object in the window global object

• neuro-min.js - Same as neuro.js but Uglified (obfuscated and compressed).

Build Your Own

---

Don't need everything in the Neuro object? Just want Neuro.Model? No problem! The pre-built files are created with WrapUp. So you can easily create your own as well!

Install Wrapup.

$ npm install -g wrapup

With Neuro installed (either locally or globally with the -g flag), create a main.js file. This file will be used to generate your own custom version of Neuro. We'll place it in a js/neuro folder. For this example, we're just going to have Neuro.Model available. Create the main.js file with the following:

exports.Model = require('Neuro/src/model/main').Model;

Finally, we want to create the built file. Run this command while in the js/neuro folder:

wrup -r Neuro ./main.js -o ./neuro.js 

And voila, a custom neuro.js file is created with Neuro object containing only the Model class.

Neuro Model

The Model is a Object-like MooTools Class object that provides a basic API to interact with data. You can use Model by itself or extend other Class objects with it. It implements each, filter, and other convenient methods from Object.

Implements:

• Mixin: Connector
• Mixin: Butler
• Mixin: Events
• Mixin: Options
• Mixin: Silence
• Mixin: Snitch

constructor (initialize)

Notes:

• Method names and properties prefixed with _ is considered private and should not be used or directly interacted with.

Returns: Model instance.

set

---

see Mixin: Snitch

setValidator

---

see Mixin: Snitch

getValidator

---

see Mixin: Snitch

validate

---

Validate will test a property in Model data against the validators defined in options.validators. If a global validator ('*' or options.validators is a function) is definined, the then the property is tested against the global validator, even if other validators are defined. A global validator can access other defined validators because the validator method is bound to this, the Model instance.

Synatx:

model.validate(property, value);

Arguments:

1. property - (String) Name of property. Should reference an existing validator. If global validator is defined, the property is passed as the first argument to the global validator.
2. value - (String | Number | Object | Boolean | Array) The value is what the validators will test against. If a global validator is defined, the value is passed as the second argument to the global validator.

Returns: Boolean

Example:

// Test against a property in validators object
var model = new Neuro.Model({}, {
    validators: {
        // Test the 'name' property to make sure it is a string
        name: Type.isString
    }
});

model.validate('name', 123); // returns false

model.validate('name', 'Bruce'); // returns true

// Test against a global validator
var model2 = new Neuro.Model({}, {
    // Test property value to be a string or number
    validators: function(prop, val){
        var type = typeOf(val);
        return type == 'string' || type == 'number';
    }
});

model2.validate('name', 'Bruce'); // returns true
model2.validate('age', undefined); // returns false
model2.validate('age', 32); // returns true

// Define a global validator to test against other defined validators
var model3 = new Neuro.Model({}, {
    validators: {
        '*': function(prop, value){
            // can only be name or age, and has to pass the validator
            return ['name', 'age'].contains(prop) && this.getValidator(prop)(value);
        },
        // Test the 'name' property to make sure it is a string
        name: Type.isString,
        // Test the 'age' property to make sure it is a number
        age: Type.isNumber
    }
});

model3.validate('birthdate', 1234); // returns false
model3.validate('birthdate', '1234'); // returns false

model3.validate('name', 123); // returns false
model3.validate('name', 'Bruce'); // returns true

model3.validate('age', '32'); // returns false
model3.validate('age', 32); // returns true

see Mixin: Snitch

proof

---

Method that proofs the model instance.

see Mixin: Snitch

Syntax:

model.proof();

Returns: (Boolean) Every property in the _validators object must exist in the model instances _data object and every function in _validators must return true in order for proof to return true, otherwise false.

Note: This overrides the original proof method, but makes use of it to "proof" the model instance.

MooTools-Core Object Methods

---

The following methods have been implemented from MooTools-Core Object onto Neuro Model. They take the same arguments as their Object counterparts with the exception of having to pass the model as the object to be acted upon.

• each
• subset
• map
• filter
• every
• some
• keys
• values
• getLength
• keyOf
• contains
• toQueryString

model.each(function[, bind]);
model.subset(keys);
model.map(function[, bind]);
model.filter(function[, bind]);
model.every(function[, bind]);
model.some(function[, bind]);
model.keys();
model.values();
model.getLength();
model.keyOf(property);
model.contains(value);
model.toQueryString();

Neuro Collection

The Collection is an Array-like MooTools Class object that provides a basic API to interact with multiple Models. You can use Collection by itself or extend other Class objects with it. It contains a reference to a Model Class to create a model instance when adding a data Object. The reference Model Class can be optionally replaced by a different Class that extends from Model. It implements each, filter, and some other convenient methods from Array.

Implements:

• Mixin: Connector
• Mixin: Events
• Mixin: Options
• Mixin: Silence
• Mixin: Snitch

constructor (initialize)

---

Syntax:

var collection = new Neuro.Collection(data [, options]);

Arguments:

1. data - (Mixed, optional)
   • Model - A Model instance
   • Object - An object of key/value pairs that will be used to create a model instance
   • Array - An array of Model instances or object key/value pairs
2. options - (Object, optional)
   • primaryKey - (String) Define to uniquely identify a model in a collection
   • Model - (Model, defaults to undefined) The Model Class used to create model instances from when an Object is passed to add.
   • modelOptions - (Object, defaults to undefined) An Object containing options for creating new model instances. See Neuro Model
   • connector - (Object) See Mixin: Connector
   • validators - (Object) See Mixin: Snitch

Returns: Class instance.

Events:

• change: function(collection){} - Triggered when there is a change in the collection (add, remove, replace).
• change:model: function(collection, model){} - Triggered when there is a change in a model. Does not trigger the change event on the collection.
• add: function(collection, model){} - Triggered when a model is added to the collection.
• remove: function(collection, model){} - Triggered when a specific model is removed from the collection.
• empty: function(collection){} - Triggered when the collection is emptied of all models.
• sort: function(collection){} - Triggered when sort or reverse occurs.
• error: function(collection, model, at){} - Triggered when a model is added to the collection that does not pass validation IF validators exist in the collection instance.

Notes:

• Method names and properties prefixed with _ is considered private and should not be used or directly interacted with.
• A default model is defined in the Collection Class as the _Model property. It can be overriden by options.Model or when a Class extends from Collection and defines a different _Model property.
• Define options.primaryKey to better identify model instances, such as checking if the collection hasModel.

Returns: Model instance.

hasModel

---

Checks if the collection instance contains a model by checking if the model exists in the _models array or using options.primaryKey to compare models.

Syntax:

currentCollection.hasModel(model);

Arguments:

1. model - (Object | Model) An Object or Model instance that is used to compare with existing models in the collection. options.primaryKey will be used to compare against the models if an initial use of Array.contains returns false.

Returns: Boolean.

add

---

Adding a model to the collection should always go through this method. It appends the model to the internal _model array and triggers the add event if the collection does not already contain the model. change event is triggered afterwards.

If _validators exist, then each model or object added must pass validation in order to be added to the collection instance. Otherwise a error event will be triggered.

If an Object is passed in, the Object will be converted to a model instance before being appended to _model. Adding a model will increase the collections length property.

It is possible to insert a model instance into _model at a specific index by passing a second argument to add.

A remove method is attached to the models destroy event so that the model can be properly removed if the model destroy event is triggered.

Syntax:

currentCollection.add(models, at);

Arguments:

1. models - (Object | Model | Array)
   • Object - An Object with key/value pairs of data properties. It will be converted to a Model instance before adding to _model.
   • Model - A Model instance.
   • Array - An Array that contain a mix of Object and Model instances.
2. at - (Number, optional) The index to insert the model in the _model array. If the collection is empty, at is ignored and and the model is inserted as the first item in the array.

Returns: Class instance.

Triggered Events:

• add
• error
• change

Examples:

currentCollection.add({
    id: 1, name: 'Bruce Lee'
}, 2);

currentCollection.add( new Neuro.Model({id: 1, name: 'Bruce Lee'}) );

currentCollection.add(
    [
        {id: 1, name: 'Bruce Lee'}, 
        new Neuro.Model({id: 1, name: 'Chuck Norris'})
    ]
);

get

---

Get the model by index. Multiple indexes can be passed to get to retrieve multiple models.

Syntax:

currentCollection.get(index);

Arguments:

1. index - (Number) The index number of the model to return.

Returns: A model instance corresponding to the index in _model. If multiple indexes are passed to get, an Array of models is returned, where each model corresponds to the index.

Examples:

currentCollection.get(0); // returns the model instance that corresponds to the index argument

currentCollection.get(0, 2, 3); // returns an array of model instances where each model corresponds to each index argument

remove

---

Remove a model or models from the collection. It will trigger the remove event for each individual model removed. change event is triggered afterwards.

The collection should remove the model only if it exists on the collection. Removing the model from the collection will also remove the remove method from the models destroy event.

Syntax:

currentCollection.remove(model);

Arguments:

1. model - (Model | Array) A model or array of models that will be removed from _model.

Returns: Class instance.

Triggered Events:

• remove
• change

Examples:

var model = new Neuro.Model({id: 1, name: 'Garrick'});

currentCollection.add(model);

currentCollection.remove(model);

//or

currentCollection.remove([model]); // remove an array of models.

replace

---

Replace an existing model in the collection with a new one if the old model exists and the new model does not exist in the collection _model array. This will trigger add and remove events. change event is triggered afterwards.

Syntax:

currentCollection.replace(oldModel, newModel);

Arguments:

1. oldModel (Model) - The model that will be replaced in the collection.
2. newModel (Object | Model) - The new model that will be replacing the old one.

Returns: Class instance.

Triggered Events:

• add
• remove
• change

sort

---

Sort the collection. Works the same way Array.sort would work. Triggers sort event.

Syntax:

currentCollection.sort(function);

Arguments:

1. function - (Function, optional) The function acts as a comparator. Please see Array.sort for more information.

Returns: Class instance.

Triggered Events:

• sort

Examples:

// Sorts models ordered by id, where id is a number.
// This function sorts the order from smallest to largest number.

currentCollection.sort(function(modelA, modelB){
    return modelA.get('id') - modelB.get('id');
});

reverse

---

Reverses the order of the collection. Works the same way Array.reverse would work. Triggers sort event.

Syntax:

currentCollection.reverse();

Returns: Class instance.

Triggered Events:

• sort

empty

---

Empty the collection of all models. Triggers the empty event and remove event for each model removed.

Syntax:

currentCollection.empty();

Returns: Class instance.

Triggered Events:

• remove for each model removed
• empty

toJSON

---

Returns a copy of collection _model. Can be used for persistence, serialization, or augmentation before passing over to another object. JSON.stringify uses this to to create a JSON string, though the method itself does not return a String.

Syntax:

currentCollection.toJSON();

Returns: Object containing the collection _model.

attachModelEvents

---

Attach handlers to the model destroy and change listeners. The model destroy event will trigger the collection remove method. The model change event will trigger the collection change:model event. This is automatically used during add to help clean up if the model is destroyed and to notify listeners of the collection that a model changed.

Syntax:

currentCollection.attachModelEvents(model);

Arguments:

• model - (Model) A model instance to attach events to.

Examples:

var model = new Neuro.Model();

currentCollection.add(model); // Events attached to the model

currentCollection.length; // Return 1, meaning there is one model existing

model.destroy(); // currentCollection is notified that to remove the model since `destroy` event was triggered

currentCollection.length // Return 0, the model was removed when it was destroyed.

Returns: Class instance.

detachModelEvents

---

Detach handlers to the model destroy and change listeners. If the model destroy event is triggered, the collection is notified and removes the model from the collection. The destroy and changeevents are removed from the model during execution of remove method.

Syntax:

currentCollection.detachModelEvents(model);

Arguments:

• model - (Model) A model instance to attach events to.

Examples:

var model = new Neuro.Model();

currentCollection.add(model); // Events attached to the model

currentCollection.length; // Return 1, meaning there is one model existing

model.destroy(); // currentCollection is notified that to remove the model since `destroy` event was triggered

currentCollection.length // Return 0, the model was removed when it was destroyed.

Returns: Class instance.

MooTools-Core Array Methods

---

The following methods have been implemented from MooTools-Core Array onto Neuro Collection. They take the same arguments as their Object counterparts with the exception of having to pass the collection as the object to be acted upon.

• forEach
• each
• invoke
• every
• filter
• clean
• indexOf
• map
• some
• associate
• link
• contains
• getLast
• getRandom
• flatten
• pick

Neuro View

The View is a MooTools Class object. It acts as a layer between an element and everything else. One of the usual conventions of plugins that deals with elements has to attach/detach events to/from the element. The View provides a simple, yet basic, way of binding methods/functions to the element event listeners.

Another convention is that attaching event handlers to classes can be a manual process. View implements the Connector utility class to provide a powerful and automatic way to attach events between two classes.

The render method is the main method that should be used to visualize the element with data. The method is basic, triggering the render event on the View class. Other class objects should extend from the View class and override the render method, but call this.parent in order to trigger the render event.

Implements:

• Mixin: Connector
• Mixin: Events
• Mixin: Options
• Mixin: Silence

constructor (initialize)

---

Starts out with executing setup and then triggering ready event.

Syntax:

var view = new Neuro.View(options);

Arguments:

1. options - (Object, optional) The View options
   • element - (String | Element, defaults to undefined) The root/parent element of where the rendered elements should be placed.
   • events - (Object, defaults to undefined) An Object of key/value pairs
     • key - (String) The element event or event-delegate type. click or click:relay(selector)
     • value - (String | Function | Array) The handler that is attached to the event. It can be a String (amethod name in the view class instance), Function, or an Array of containing a mix of String or Function items.
   • connector - (Object) See Mixin: Connector

Returns: View instance..

Events:

• ready: function(view){} - Triggered at the end of the setup method.
• render: function(view){} - Triggered at the end of the render method.
• inject: function(view){} - Triggered at the end of the inject method.
• dispose: function(view){} - Triggered at the end of the dispose method.
• destroy: function(view){} - Triggered at the end of the destroy method.

Notes:

• Method names and properties prefixed with _ is considered private and should not be used or directly interacted with.

setup

---

Called during initialize to setOptions, and setElement.

Arguments:

• Same as initialize

Returns: View instance.

toElement

---

A method to retrieve the element stored in the view instance. Any Class instance, with a toElement method, passed to MooTools Element document.id or $ method will return the value from the classes toElement method. This is a hidden MooTools Core trick.

Syntax:

view.toElement();

document.id(view);

$(view);

Returns: element property stored in view instance.

setElement

---

Store the root element for the view instance. If an element exists, it will first execute View destroy method to properly detach events and remove references to it. Then it will store a reference to the element and execute View attachEvents.

Syntax:

view.setElement(element);

Arguments:

1. element - (Element) Element to be set as root element in the view instance. attachEvents will refer to options.events for the event and method/function to attach.

Returns: View instance.

attachEvents

---

Attach events to the root element property in the view instance. It refers to options.events to map element events to functions or methods in the view instance. Events can be detached using detachEvents. element or options.events are required to exist.

Syntax:

view.attachEvents();

Returns: View instance.

detachEvents

---

Detach events from the root element property in the view instance. It refers to options.events to map element events to functions or methods in the view instance. Events can be attached using attachEvents. element or options.events are required to exist.

Syntax:

view.detachEvents();

Returns: View instance.

create

---

It is a no-op method. Override create in your Class that extends from View. It could be used to create the root element, or other child elements that goes into the root `element.

Syntax:

view.create();

Returns: View instance.

render

---

Although render is considered a no-op method, it still trggers the render event. Override render in your Class that extends from View. Remember to call 'this.parent()' at the end of your code to execute the original render method that will trigger the render event. Pass data to the render method, such as Neuro Model or Neuro Collection.

If you are passing any Class that implements Mixin: Connector, you should consider using the connect method. It will help to automatically attach events between the View instance and the other Classes, in this case it is likely to be a Neuro Model or Neuro Collection instances.

Syntax:

view.render(data);

Arguments:

1. data - (Mixed) It can be anything you will use as data to render the view. This also means you can pass in multiple Neuro Model instances, multiple Neuro Collection instances, other View instances. Use your imagination.

Returns: View instance.

Triggered Events:

• render

inject

---

Inject or inserts the root element relative to another element or View instance. document.id / $ will resolve the element from the other View instance.

Syntax:

view.inject(reference[, where]);

Arguments:

1. reference - (String | Element | Class) The element will be placed relative to the reference element. A String should be the id of the reference element, without the "#". A Class instance should have a toElement method in order to resolve the reference element.
2. where - (String, optional, defaults to "bottom") The place to inject/insert the element relative to the reference element. Can be: top, bottom, after, or before.

Returns: View instance.

Triggered Events:

• inject

dispose

---

Removes the Element from the DOM but retains it in memory if the element exists.

Syntax:

view.dispose();

Returns: View instance.

Triggered Events

• dispose

destroy

---

Removes the Element and its children from the DOM and prepares them for garbage collection. Executes detatchEvents and removes reference to element in element property. Triggers destroy event.

Syntax:

view.destroy();

Returns: View instance.

Neuro Route

The Route is a Class object that extends from the Model class object. It is heavily influenced by Crossroads.js by Miller Medeiros, as well as the documentation for it. A Route instance provides methods, amongst others, to test, parse, and interpolate data against a pattern.

Extends: Model

Implements:

• Mixin: Connector
• Mixin: Butler
• Mixin: Events
• Mixin: Options
• Mixin: Silence
• Mixin: Snitch

constructor (initialize)

---

Syntax

var route = new Neuro.Route(data [, options]);

Arguments:

1. data - (Object) An object containg key/value pairs. The properties in the data have default values.

   • pattern - (String | Regexp, optional, defaults to undefined) String pattern or Regular Expression that should be used to match against requests.

     If pattern is a String it can contain named variables surrounded by '{}' that will be evaluated and passed to handlers as parameters. Each pattern segment is limited by the '/' char, so named variables will match anything until it finds a '/' char or the next string token located after the variable.

     The pattern '{foo}/{bar}' will match 'lorem/ipsum-dolor' but won't match 'lorem/ipsum-dolor/sit'. Trailing slashes at the end/begin of the request are ignored by default, so /{foo}/ matches same requests as {foo}. - If you need to match segments that may contain "/" use a regular expression instead of a string pattern.

     A pattern can also have optional segments, which should be surrounded by :: (e.g. 'news/:foo:/:bar:' will match 'news', 'news/123' and 'news/123/asd').

     If pattern is a RegExp, capturing groups will be passed as parameters to handlers on the same order as they were matched.

     It also allows "rest" segments (ending with *) which can match multiple segments. Rest segments can be optional and/or required and don't need to be the last segment of the pattern. The pattern '{foo}/:bar*:' will match news 'news/123', 'news/123/bar', 'news/123/lorem/ipsum'.

     Support has been added to decoding query strings as well by starting the capturing groups with a '?' (eg: {?foo}, :?bar:). The matched value will be converted into an object.

   • callback - (Function, optional, defaults to undefined) Function that should be executed when a request matches the Route pattern. It's just a convenient way to attach a handler to the match event.

   • priority - (Number, optional, defaults to undefined) Route execution priority.

     Routes with higher priority will be tested during Neuro.Router.parse. It is important to note that Neuro.Router will stop pattern tests as soon as it finds a Route that matches the request. Setting the priority is a way to invert “natural” test order. Routes are tested by order of creation if priority is omitted.

   • normalizer - (Function, optional, defaults to undefined) A function that should be used to normalize parameters. Works similarly to Route rules.normalize_. normalizer will be used if rules.normalizer_ does not exist. If both normalize functions do not exist, then, obviously, normalizing parameters will not occur.

   • greedy - (Boolean, optional, defaults to false) Used to determine whether Neuro.Router should try to match this Route instance after having matched another Route instance.

     Neuro.Router will trigger all "greedy" Routes that match the request during parse in the Neuro.Router instance.

   • rules - (Model, Object, optional, defaults to {}) Object used to configure parameters/segments validation rules.

     Validation rules can be an Array, a RegExp or a Function:

     • If rule is an Array, crossroads will try to match a request segment against items of the Array, if item is found parameter is valid.
     • If rule is a RegExp, crossroads will try to match a request segment against it.
     • If rule is a Function, crossroads will base validation on value returned by Function (should return a Boolean).

     Rules keys should match route pattern segment names or should be a numeric value, starting at index 0, that match each RegExp capturing group or path segment.

     The rules object can also contain 2 special properties request_ and normalize_:

     • normalizer_ - (Function(request, values), optional) Used to modify/normalize values before triggering the match event by Neuro.Router. It should return an Array with parameters that should be passed to listeners.

       Can be used to create route aliases and also to convert data format.

       Works exactly like options.modelOptions.defaults.normalizer in Neuro.Router. It will overwrite options.modelOptions.defaults.normalizer in Neuro.Router if present.

     • request_ - (Array | RegExp | Function) Rule used to validate whole request. request_ is a special rule used to validate whole request Note that request will be typecasted if value is a boolean or number and options.modelOptions.defaults.typecast = true (default = false) in Neuro.Router.

   • typecast - (Boolean, optional, defaults to false) Type cast route paths with this property. true typecasts values in the route path, while false typecasts them as strings.

   • patternLexer - (Object, optional, defaults to Route.PatternLexer) The pattern lexer is undefined. Mixin: Butler, the custom accessor, allows defining a custom pattern lexer for each individual route, but defaults to using the global Route.PatternLexer.

2. options - (Object, optional) See Model.

Returns: Route instance.

Events (Includes events inherited from Neuro.Model):

• match: function(route[, param1, param2, param3...]){} - Triggered when Neuro.Router has found a match. Neuro.Router will pass each captured parameter to the handler function.
• pass: function(route[, request]){} - Triggered when Neuro.Router has changed from one route to the next. The request parameter passed to the event refers to the current request that is being changed to.

Examples:

// Create a new route with a pattern
var route = new Neuro.Router.Route({
    pattern: 'person/{name}'
});

// Test a string against the route
route.match('person/bruce'); // returns true
route.match('person/bruce/lee'); // returns false

match

---

Test if the Route instance matches against a string.

Syntax:

route.match(string);

Arguments:

1. string - (String) The string which will be tested against he Route instances rules and pattern.

Returns: Boolean (true/false).

Examples:

// Create a new route with a pattern
var route = new Neuro.Router.Route({
    pattern: 'person/{name}'
});

// Test a string against the route
route.match('person/bruce'); // returns true
route.match('person/bruce/lee'); // returns false

parse

---

Parse a string for matches against the Route instances pattern.

Syntax:

route.parse(string);

Arguments:

1. string - (String) The string which will be parsed for matches against the Route instances pattern.

Returns:

• Found matches
  • An array of matched items
• No matches
  • null

Examples:

// Create a new route with a pattern
var route = new Neuro.Router.Route({
    pattern: 'person/{name}'
});

route.parse('person/bruce'); // returns ['bruce']
route.parse('person/bruce/lee'); // returns null

interpolate

---

Generates a string that matches the route by replacing captured groups in the Route instances pattern with the replacements values provided.

Syntax:

route.interpolate(replacements);

Arguments:

1. replacements - (Object) Contains key/value pairs to match and replace captured groups in the pattern.

Returns: String.

Examples:

// Create a new route with a pattern
var route = new Neuro.Router.Route({
    pattern: 'person/{name}'
});

route.interpolate({name: 'awesome'}); // returns 'person/awesome'

Neuro Router

The Router is a Class object that extends from the Collection class object. It is heavily influenced by Crossroads.js by Miller Medeiros, as well as the documentation for it. It parses string input to decide what action should be taken by matching the string against mutiple patterns (Route instances).

Extends: Collection

Implements:

• Mixin: Connector
• Mixin: Events
• Mixin: Options
• Mixin: Silence
• Mixin: Snitch

constructor (initialize)

---

Syntax:

var router = new Neuro.Router(routes[, options]);

Arguments:

1. routes - (Mixed, optional)
   • Route - A Route instance.
   • Object - An object of key/value pairs that will be used to create a Route instance.
   • Array - An array of Route instances or object key/value pairs.
2. options - (Object, optional) See Collection for the other options inherited from Collection

   • modelOptions - (Object, optional) Sets the options for Route instances during the add method call. Check Neuro Model

     • defaults - (Object, optional) Sets the default properties for Route instances during the add method call. Check Neuro Route for the properties

   • greedy - (Boolean, optional, defaults to false) Set to false will stop on the first match with the supplied request.

     Set to true will try to match every single Route instance with the supplied request.

   • greedyEnabled - (Boolean, optional, defaults to true) If false it won't try to match multiple routes (faster).

Returns: Route instance.

Events:

• match: function(router, request, data){} - Triggered when Router instance finds a match during parse().
  • router - (Router) The Router instance.
  • request - (String) The string being parsed.
  • data - (Object) Contains data pertaining to matching Route instance.
    • route - (Route) The matching Route instance
    • params - (Array) An array containing parameters captured by the Route instances pattern
    • isFirst - (Boolean) true for the first time match event is triggered during the parse() method call. Will be false unless the Route instance is greedy and it is being matched after another Route instance already matched the request.
• default: function(router, request){} - Triggered when Router instance does not find a match during parse().
  • router - (Router) The Router instance.
  • request - (String) The string being parsed.

Examples:

/*
Create a router instance. Note the typecast property in modelOptions.defaults object.
This will typecast the captured group so that rules can be simple functions like Type.isString.
Otherwise all values passed to the rules will be strings.
 */
var router = new Neuro.Router([{
    pattern: 'news/{id}',
    rules: {
        id: Type.isNumber
    }
}], {
    onMatch: function(router, request, data){
        console.log('match', request, data);
    },
    onDefault: function(router, request){
        console.log('default', request);
    },
    modelOptions: {
        defaults: {
            typecast: true
        }
    }
});

/*
typecast property needs to be manually set here because modelOptions object is only
used when a Route instance is created by the Router instance during the add method call.
 */
router.add( new Neuro.Router.Route({
    pattern: 'news/{type}/{id}',
    rules: {
        type: Type.isString,
        id: Type.isNumber
    },
    typecast: true
}) );

// triggers default event
router.parse('news');

// triggers default event because 'a' is typecast as a string
router.parse('news/a');

// triggers match on the 'news/{id}' pattern because '123' is typecast to a number and passes the rule for 'id'
router.parse('news/123');

// triggers default event because '123' is typecast as a number and does not pass the 'type' rule for 'news/{type}/{id}' pattern
router.parse('news/123/456');

// triggers match on the 'news/{type}/{id}' pattern because 'abc' is typecast to a string and passes the rule for 'type'
// and '456' is typecast as a number and passes the rule for 'id'
router.parse('news/abc/456');

parse

---

Parse a string input and trigger the first matching Route instances match event. Routing priority is defined by order of insertion or by the priority property of each Route instance.

Syntax:

router.parse(request[, defaultArgs]);

Arguments:

1. request - (String) String that should be evaluated and matched against Route instances to define which Route match event handlers should be executed and which parameters should be passed to the match event handlers.
2. defaultArgs - (Array, optional) Array containing values passed to match/default signals as first arguments. Useful for node.js in case you need to access the request and response objects.

Returns: Router instance.

Events:

• pass
• Route instance match
• match
• default

Notes:

The parse algorithm is very straightforward, since the string patterns were already converted into regular expressions during add method call the router just need to loop through all the routes (following the priority order) and check which one matches the current input. If it does find a route that matches the request it will check if the route contains the special property rules and then it will validate each segment (capturing group). If after all that the route is considered "matched", then the previous Route's pass event is triggered and the Route match event is triggered together with the Router's match event. Otherwise the Router's default event is triggered.

Calling parse multiple times in a row passing the same request will trigger the match/Route instance match/default signals only once.

Examples:

/*
typecast property needs to be manually set here because modelOptions object is only
used when a Route instance is created by the Router instance during the add method call.
 */
var route1 = new Neuro.Router.Route({
    pattern: 'news/{id}',
    rules: {
        id: Type.isNumber
    },
    // the 'match' event handler on the route
    callback: function(route, id){
        console.log('Router match news/id', id);
    },
    typecast: true
});

route1.addEvent('pass', function(request){
    console.log('Passed to ' + request);
});

var route2 = new Neuro.Router.Route({
    pattern: 'news/{type}/{id}',
    rules: {
        type: Type.isString,
        id: Type.isNumber
    },
    // the 'match' event handler on the route
    callback: function(route, type, id){
        console.log('Router match news/type/id', type, id);
    },
    typecast: true
});

route2.addEvent('pass', function(request){
    console.log('Passed to ' + request);
});

/*
Create a router instance. Note the typecast property in modelOptions.defaults object.
This will typecast the captured group so that rules can be simple functions like Type.isString.
Otherwise all values passed to the rules will be strings.
 */
var router = new Neuro.Router([route1, router2]);

/*
router 'default' event is triggered.
 */
router.parse('news');

/*
route1 'match' event is triggered.
router 'match' event is triggered.
no 'pass' event is triggered because there was no matching route in the previous parse method call.
 */
router.parse('news/123');

/*
route1 'pass' event is triggered.
route2 'match' event is triggered.
router 'match' event is triggered.
 */
router.parse('news/abc/123');

resetState

---

Resets the Router instances internal state. Will clear reference to previously matched Route instances (so they won't trigger pass events when matching a new route) and reset last request.

This feature should NOT be needed by most users.

Syntax:

router.resetState();

Returns: Router instance.

Examples:

var route1 = new Neuro.Router.Route({
    pattern: 'news/{id}',
    rules: {
        id: Type.isNumber
    },
    // the 'match' event handler on the route
    callback: function(route, id){
        console.log('Router match news/id', id);
    },
    typecast: true
});

route1.addEvent('pass', function(request){
    console.log('Passed to ' + request);
});

var route2 = new Neuro.Router.Route({
    pattern: 'news/{type}/{id}',
    rules: {
        type: Type.isString,
        id: Type.isNumber
    },
    // the 'match' event handler on the route
    callback: function(route, type, id){
        console.log('Router match news/type/id', type, id);
    },
    typecast: true
});

route2.addEvent('pass', function(request){
    console.log('Passed to ' + request);
});

/*
Create a router instance. Note the typecast property in modelOptions.defaults object.
This will typecast the captured group so that rules can be simple functions like Type.isString.
Otherwise all values passed to the rules will be strings.
 */
var router = new Neuro.Router([route1, router2]);

/*
route1 'match' event is triggered.
no 'pass' event is triggered because there was no matching route to begin with.
 */
router.parse('news/123');

/*
route1 'pass' event is triggered.
route2 'match' event is triggered.
 */
router.parse('news/abc/123');

// Remove references to previous request and route
router.resetState();

/*
route1 'match' event is triggered.
no 'pass' event is triggered references to previous request and route have been removed.
 */
router.parse('news/123');

Mixin: Events

---

From MooTools Documentation: A Utility Class. Its methods can be implemented with Class:implement into any Class. Events in a Class that implements Events must be either added as an option or with addEvent, not directly through .options.onEventName.

Syntax:

For new classes:

var MyClass = new Class({ Implements: Events });

For existing classes:

MyClass.implement(Events);

Implementing:

• This class can be implemented into other classes to add its functionality to them.
• Events has been designed to work well with the Options class. When the option property begins with 'on' and is followed by a capital letter it will be added as an event (e.g. onComplete will add as complete event).

Example:

var Widget = new Class({
    Implements: Events,
    initialize: function(element){
        // ...
    },
    complete: function(){
        this.fireEvent('complete');
    }
});

var myWidget = new Widget();
myWidget.addEvent('complete', myFunction);

Notes:

• Events starting with 'on' are still supported in all methods and are converted to their representation without 'on' (e.g. 'onComplete' becomes 'complete').

addEvent

---

Adds an event to the Class instance's event stack.

Syntax:

myClass.addEvent(type, fn[, internal]);

Arguments:

1. type - (String) The type of event (e.g. complete).
2. fn - (Function) The function to execute.
3. internal - (Boolean, optional) Sets the function property: internal to true. Internal property is used to prevent removal.

Returns: This Class instance.

Example:

var myFx = new Fx.Tween('element', 'opacity');
myFx.addEvent('start', myStartFunction);

addEvents

---

The same as addEvent, but accepts an object to add multiple events at once.

Syntax:

myClass.addEvents(events);

Arguments:

1. events - (Object) An object with key/value representing: key the event name (e.g. start), and value the function that is called when the Event occurs.

Returns: This Class instance.

Example:

var myFx = new Fx.Tween('element', 'opacity');
myFx.addEvents({
    start: myStartFunction,
    complete: function() {
        alert('Done.');
    }
});

fireEvent

---

Fires all events of the specified type in the Class instance.

Syntax:

myClass.fireEvent(type[, args[, delay]]);

Arguments:

1. type - (String) The type of event (e.g. complete).
2. args - (String | Array, optional) The argument(s) to pass to the function. To pass more than one argument, the arguments must be in an array.
3. delay - (Number, optional) Delay in milliseconds to wait before executing the event (defaults to 0).

Returns: This Class instance.

Example:

var Widget = new Class({
    Implements: Events,
    initialize: function(arg1, arg2){
        //...
        this.fireEvent('initialize', [arg1, arg2], 50);
    }
});

removeEvent

---

Removes an event from the stack of events of the Class instance.

Syntax:

myClass.removeEvent(type, fn);

Arguments:

1. type - (String) The type of event (e.g. complete).
2. fn - (Function) The function to remove.

Returns: This Class instance.

Notes:

• If the function has the property internal and is set to true, then the event will not be removed.

removeEvents

---

Removes all events of the given type from the stack of events of a Class instance. If no type is specified, removes all events of all types.

Syntax:

myClass.removeEvents([events]);

Arguments:

1. events - (optional) If not passed removes all events of all types.
   • (String) The event name (e.g. 'success'). Removes all events of that type.
   • (Object) An object of type function pairs. Like the one passed to addEvents.

Returns: This Class instance.

Example:

var myFx = new Fx.Tween('myElement', 'opacity');
myFx.removeEvents('complete');

Notes:

• removeEvents will not remove internal events. See Events:removeEvent.

Mixin: Options

---

From MooTools Documentation: A Utility Class. Its methods can be implemented with Class:implement into any Class. Used to automate the setting of a Class instance's options. Will also add Class Events when the option property begins with 'on' and is followed by a capital letter (e.g. onComplete adds a complete event). You will need to call this.setOptions() for this to have an effect, however.

Syntax:

For new classes:

var MyClass = new Class({Implements: Options});

For existing classes:

MyClass.implement(Options);

setOptions

---

Merges the default options of the Class with the options passed in. Every value passed in to this method will be deep copied. Therefore other class instances or objects that are not intended for copying must be passed to a class in other ways.

Syntax:

myClass.setOptions([options]);

Arguments:

1. options - (Object, optional) The user defined options to merge with the defaults.

Returns: This Class instance.

Example:

var Widget = new Class({
    Implements: Options,
    options: {
        color: '#fff',
        size: {
            width: 100,
            height: 100
        }
    },
    initialize: function(options){
        this.setOptions(options);
    }
});

var myWidget = new Widget({
    color: '#f00',
    size: {
        width: 200
    }
});

//myWidget.options is now: {color: #f00, size: {width: 200, height: 100}}

// Deep copy example
var mySize = {
    width: 50,
    height: 50
};

var myWidget = new Widget({
    size: mySize
});

(mySize == myWidget.options.size) // false! mySize was copied in the setOptions call.

Notes:

• Relies on the default options of a Class defined in its options property.

Options in combination with Events

If a Class has Events as well as Options implemented, every option beginning with 'on' and followed by a capital letter (e.g. onComplete) becomes a Class instance event, assuming the value of the option is a function.

Example:

var Widget = new Class({
    Implements: [Options, Events],
    options: {
        color: '#fff',
        size: {
            width: 100,
            height: 100
        }
    },
    initialize: function(options){
        this.setOptions(options);
    },
    show: function(){
        // Do some cool stuff

        this.fireEvent('show');
    }

});

var myWidget = new Widget({
    color: '#f00',
    size: {
        width: 200
    },
    onShow: function(){
        alert('Lets show it!');
    }
});

myWidget.show(); // fires the event and alerts 'Lets show it!'

Mixin: Connector

---

A Utility Class. It allows automatic attachment/detachment of event listeners between two classes.

options.connector

---

A key/value object to map events to functions or method names on the target class that will be connected with. The value can also be an object that contains more key/value pairs. This allows to attach sub-events, such as change:key. Note: An asterisk (*) as the sub-event refers to the parent event only.

Note: Using a nested object in options.connector as the map is possible via a name param when using connect or disconnect. Doing so means that connecting/disconnecting the class will ALWAYS have to designate the name param. If you don't, then issues will occur because then Connector will treat nested objects key/value pairs as sub-events.

Implements: PowerTools! Class.Binds

Syntax: key/value pairs

// Shallow object
{
    event: method
}

// Nested object
{
    name: object
}

Arguments

• Shallow object
  1. event - (String) The name of the event to be attached. It becomes the parent event if the events corresponding value is an object.
  2. method - (String, Function, Array, Object)
     • String - Refers to a method on the target class. The method will be bound to the target class and attached as the event handler.
     • Function - The function will be bound to the current class and attached as the event handler
     • Array - Can contain a mix of String (name of method to retrieve said method from target class) or Function to be attached as the event handler
     • Object - Contains key/value pairs where key will refer to the sub-event and value refers to String, Function, or Array to attach as event handlers. The sub-event will be prepended by the event with a :.
• Nested Object
  1. name - (String) Name of the object that would be used as the map during connect/disconnect
  2. object - (Object) The shallow object that is used as the map during connect/disconnect

Examples

The following will show what key/value pairs will look like and what they look like when attached manually instead of with connector.

• value is a string

change: 'doneMethodName'

currentClass.addEvent('change', targetClass.doneMethodName.bind(targetClass));

• value is a function

change: function(){/*... code here ...*/}

currentClass.addEvent('change', function(){/*... code here ...*/});

• value is an array

change: ['doneMethodName', function(){/*... code here ...*/}]

currentClass.addEvent('change', targetClass.doneMethodName.bind(targetClass));

currentClass.addEvent('change', function(){/*... code here ...*/});

• value is an object with subevents and a mix of string, function, or array.

change: {
    '*': 'doneMethodName',
    'name': function(){/*... code here ...*/},
    'age': ['otherDoneMethodName', function(){/*... other code here ...*/}]
}

currentClass.addEvent('change', targetClass.doneMethodName.bind(this));

currentClass.addEvent('name', function(){/*... code here ...*/});

currentClass.addEvent('age', targetClass.otherDoneMethodName.bind(targetClass));

currentClass.addEvent('age', function(){/*... other code here ...*/});

connect

---

Connects two classes by using options.connector as the map to either attach event listeners to functions on options.connector or methods on the target class where the method names are retrieved from options.connector. Default behavior is to connect one class. Connect both ways by passing a second argument as true.

A name of a specific object in options.connector can be passed as the second argument and that object will be used as the map. If connecting both ways, the same name will be used. Connect both ways by passing a third argument as true.

Syntax

currentClass.connect(targetClass[, twoWay]);

currentClass.connect(targetClass[, name[, twoWay]]);

Arguments

1. class - (Class) The class containing the methods that will be attached as event handlers to event listeners on the current class.
2. name - (String, optional) Name of a specific object in options.connector to be used as the map.
3. oneWay - (Boolean, optional, false by default) Set to true will only connect this class with the target class and will not have the target class connect with this class.

Returns: Class instance.

Examples:

// Using options.connector object by default
currentClass.options.connector = {
    'add': 'doAddStuff'
};

targetClass.options.connector = {
    'remove': 'doRemoveStuff'
};

/**
 * Bind one way.
 *
 * Basically does currentClass.addEvent('add', targetClass.doAddStuf.bind(targetClass));
 */
currentClass.connect(targetClass);

/**
 * Bind both ways.
 * Basically does:
 * 
 * currentClass.addEvent('add', targetClass.doAddStuf.bind(targetClass))
 * and
 *
 * targetClass.addEvent('remove', currentClass.doRemoveStuff.bind(currentClass));
 */
currentclass.connect(targetClass, true);

// Using specific object that is nested in options.connector
currentClass.options.connector = {
    'classSpecific': {
        'add': 'doAddStuff'
    }
};

targetClass.options.connector = {
    'classSpecific': {
        'remove': 'doRemoveStuff'
    }
};

/**
 * Bind one way.
 *
 * Basically does currentClass.addEvent('add', targetClass.doAddStuf.bind(targetClass));
 */
currentClass.connect(targetClass, 'classSpecific');

/**
 * Bind both ways.
 * Basically does:
 * 
 * currentClass.addEvent('add', targetClass.doAddStuf.bind(targetClass))
 * and
 *
 * targetClass.addEvent('remove', currentClass.doRemoveStuff.bind(currentClass));
 */
currentclass.connect(targetClass, 'classSpecific', true);

disconnect

---

Does the opposite of what connect does. Takes the same arguments.

bound

---

A method provided by PowerTools! Class.Binds.

Provides an alternative way to bind class methods. Stores references to bound methods internally without any manual setup and does not modify the original methods.

The retrieved function is bound to the class instance.

Syntax:

currentClass.bound(methodName);

Arguments:

1. methodName - (String) Name of the method that has been bound to the class instance and stored.

Examples: (Slightly modified from PowerTools! Class.Binds)

var currentClass = new Class({
    Implements: Connector,

    initialize: function(element){
        this.element = document.id(element);

        this.attach();
    },

    attach: function(){
        // Add the click method as event listener
        this.element.addEvent('click', this.bound('click'));
    },

    detach: function(){
        // Retrieves the same reference to the click method and removes the listener
        this.element.removeEvent('click', this.bound('click'));
    },

    click: function(event){
        event.preventDefault();

        // doSomething
        this.refersToTheClassInstance();
    }
});

Mixin: Butler

---

A Utility Class. It provides a way to define custom setters/getters on a Class.

options.accessors

---

A key/value object where the key is the name of the setter and value is an object containing overriding set/get methods.

Syntax: key/value pairs

name: {
    set: function,
    get: function
}

Arguments

1. name - (String) Name of the set/get method that will get overriden
2. object - (Object) Contains set, get method overrides.
   • set - (Function) The overriding set function. The function will be bound to the current class.
   • get - (Function) The overriding get function. The function will be bound to the current class.

setupAccessors

---

Existing accessors in _accessors are merged with options.accessors before being sent to setAccessor. This should be called in the initailize or setup method.

Syntax:

currentClass.setupAccessors();

Returns: Class instance.

isAccessing

---

Check whether an accessor is being used by checking if _accessorName has been defined. This will allow a class to bypass recursive calls to the same custom setter/getter.

Syntax:

currentClass.isAccessing();

Returns: Boolean

setAccessor

---

A method to decorate custom setters/getters that will allow the use of isAccessing to prevent recursive calls to the same custom setter/getter. The decorated custom setters/getters is an object of name/function pairs that is stored in _accessors by name.

Syntax:

currentClass.setAccessor(name, obj);

currentClass.setAccessor(obj);

Arguments:

• Two Arguments
  1. name - (String) Name of the accessor setter/getter object.
  2. obj - (Object) Key/value pairs where the key is set or get and value is the function. Any key/value pair is optional. A set can exists without a get, and a get can exist without a set.

Returns: Class instance.

Note: The original undecorated function is stored on the decorated function in the _orig attribute.

Example:

var klass = new Class({
    Implements: CustomAccessor,

    options: {
        accessors: {
            fullName: {
                set: function(){}
            }
        }
    }
});

var currentClass = new klass();

// manually executed because klass doesn't have an initialize or setup method to execute setupAccessors.
currentClass.setupAccessors();

var fullNameAccessor = currentClass.getAccessor('fullName');

fullNameAccessor.set; // returns the decorated set function.

fullNameAccessor.set._orig // is the undecorated original set function.

getAccessor

---

A method to retrieve stored accessors by name or by name and type.

Syntax:

currentClass.getAccessor(name[, type]);

Arguments:

1. name - (String) The name of the accessor object to return.
2. type - (String, optional) The name of the method that exists in the accessor object.

Returns:

1. Object - The object of decoerated key/value pairs containing the accessors that was stored with the name.
2. Function - The decorated function that is associated with the type in the accessor object. The accessor object is retrieved with the name.

Examples:

Return an accessor object

currentClass.setAccessor('fullName', {
    set: function(){}
});

var fullNameAccessors =  currentClass.getAccessor('fullName');
/*
fullNameAccessors returns and object where the set function is the decorated function
{
    set: function(){}
}
 */

Return the decorated function in the accessor object

// Returns the decorated function that is stored with the set key, in the fullName accessor object.
var fullNameSetAccessor = currentClass.getAccessor('fullName', 'set');

unsetAccessor

---

Remove an accessor object or decorated function from the accessor object.

Syntax:

currentClass.unsetAccessor(name[, type]);

Arguments:

1. name - (String) The name of the accessor object to remove.
2. type - (String, optional) The key of the function that should be removed from the accessor object.

Returns: Class instance.

Example

Remove an accessor object

currentClass.unsetAccessor('fullName');

Remove a function from the accessor object

currentClass.unsetAccessor('fullName', 'set');

Mixin: Silent

A Utility Class. It provides a solution to disable before a function executes, and re-enabling afterwards.

isSilent

---

Checks if the Class is currently silent.

Syntax:

currentClass.isSilent();

Returns: Boolean

silence

---

Any method that can trigger an event can be temporarily disabled by passing the function through silence. Once the function has been triggered, events will be re-enabled.

Syntax:

currentClass.silence(function);

Arguments:

1. function - (Function) The function that will be executed once events have been prevented. The function is bound to the model instance before execution.

Returns: Class instance.

Mixin: Snitch

---

A Utility Class. Use this class to set/get validator functions. A validate method offers a way to easily retrieve a validator to test a value. A proof method is a simple object spec test that tests an object for existence of keys and runs validation tests on the values of those keys.

options.validators

---

A key/value object where the key is the property name and value is a function. The function will be passed an argument to test against and should return a boolean.

Syntax: key/value pairs

{
    name: function,
    name: function
}

Arguments

1. name - (String) Name of the validator function
2. function - (Function) The function will be passed an argument to test against and should return a Boolean

setupValidators

---

Existing validators in _validators are merged with options.validators to be attached by setValidator. This should be called in the initailize or setup method.

Syntax:

currentClass.setupValidators();

Returns: Class instance.

setValidator

---

Set functions by property. The function will be decorated to be bound to the class instance.

Syntax:

currentClass.setValidator(name, function)

currentClass.setValidator(obj);

Arguments:

• Two Arugments:
  1. name - (String) Name of the validator.
  2. function - (Function) The validation function to test against a passed parameter.
• One Argument:
  1. obj - (Object) Name/function object.

Returns: Class instance.

Note: The original undecorated function is stored on the decorated function in the _orig attribute.

Example:

var klass = new Class({
    Implements: Snitch,

    options: {
        validators: {
            fullName: Type.isString // Type.isString is a method in MooTools-Core that tests arguments whether they are strings or not by returning a boolean
        }
    }
});

var currentClass = new klass();

// manually executed because klass doesn't have an initialize or setup method to execute setupValidators.
currentClass.setupValidators();

// returns the validation function
var fullNameValidator = currentClass.getValidator('fullName');

// the undecorated original function
fullNameValidator._orig;

getValidator

---

Retrieve a stored validation function by property name.

Syntax:

currentClass.getValidator(name[, name]);

Arguments

1. name - (String) The name of the validator to return. Consecutive names will return an object of name/function matches.

Returns:

• More than One Consecutive Argument
  • (Object) Name/function pairs containing matches validator functions and their corresponding names. An unexisting validator will return undefined in place of the function.
• One argument
  • (Function) Validation function corresponding to the name.

Example:

currentClass.getValidator('fullName'); // returns function or undefined

currentClass.getValidator('age', 'fullName'); // returns an object containing age and fullName properties

validate

---

Convenient method to retrieve a validator by property to test the value against. By default it always returns true. If a validator exists, it returns the results of validation.

Syntax:

currentClass.validate(property, value);

Arguments:

1. property - (String) Name of the validator to retrieve.
2. value - (Mixed) Value to validate by the retrieved validator.

Returns:

• (Boolean) Value of whether validation has passed or not.

proof

---

"Proof" an object where every item that exists in _validators exists in the object and every validation function returns a true value. This causes _validators to act like a spec. By default, proof returns true in case there are no defined validators. It is a convenient method that utilizes Snitch Function: proof;

Syntax:

currentClass.proof(obj);

Arguments:

1. obj - (Object) The object that will be tested against every validator in _validators. Every property in _validators just exist in obj and every function must pass in order for proof to return true.

Returns:

• (Boolean) Value of whether the object has passed validation and item existence.

Snitch Function: proof

---

Generic method to proof an object with validators.

Syntax:

Snitch.proof(obj, validators);

Arguments:

1. obj - (Object) Object of key/value pairs that will be compared againstvalidators
2. validators - (Object) Object of key/function pairs that will be used to compare against obj where each key has to exist in the obj and the obj property value passes the validator function.

Returns:

• (Boolean) Value of whether the object has passed validation and item existence.
