bugcore is a JavaScript library that provides a foundational architecture for object oriented JS
bugcore is a JavaScript library that provides a foundational architecture for object oriented JS. It is designed to work both within node js as well as directly in the browser.
bugcore provides a basic class model based on John Resig's simple JavaScript inheritance. In addition the library provides many basic data models and utility classes for common object oriented patterns.
The library is extremely robust and makes up the foundation of our architecture for airbug so check out the docs for an overview of the full power of what the code has to offer. If the library is missing something you need, please let us know!
NOTE: This documentation is still being written. If you click on a link and it doesn't go anywhere, it's likely because that portion of the docs hasn't been written yet. If there are parts of the docs you'd like us to focus on, feel free to ask!
Creation of a new class
var Class = bugcore.Class;
var Obj = bugcore.Obj;
var SomeClassConstructor = Class.extend(Obj, {});
Creation of a new class with an internal _constructor method
var SomeClassConstructor = Class.extend(Obj, {
_constructor: function() {
this._super(); // Call super constructor
}
});
Creation of a new class with overridden equals and hashCode methods
/**
* @class
* @extends {Obj}
*/
var SomeClassConstructor = Class.extend(Obj, {
/**
* @constructs
* @param {number} a
* @param {number} b
*/
_constructor: function(a, b) {
this._super(); // Call super constructor
/**
* @private
* @type {number}
*/
this.a = a;
/**
* @private
* @type {string}
*/
this.b = b
},
/**
* @override
* @param {*} value
* @return {boolean}
*/
equals: function(value) {
if (Class.doesExtend(value, SomeClass)) {
return (Obj.equals(value.a, this.a) && Obj.equals(value.b, this.b));
}
return false;
},
/**
* @override
* @return {number}
*/
hashCode: function() {
if (!this._hashCode) {
this._hashCode = Obj.hashCode("[SomeClass]" +
Obj.hashCode(this.a) + Obj.hashCode(this.b));
}
return this._hashCode;
},
});
Use of a Map
var myMap = new bugcore.Map();
myMap.put("key1", "value1");
myMap.put("key2", "value2");
myMap.get("key1"); // "value1"
myMap.get("key2"); // "value2"
Use of a Map with instances as keys
var myMap = new bugcore.Map();
// SomeClass is from the above example that uses overridden equals and hashCode methods
var instance1 = new SomeClass(123, "abc");
var instance2 = new SomeClass(123, "abc");
myMap.put(instance1, "value");
myMap.put(instance2, "value2");
//hash codes and equality checks are equal therefore the two instances are considered
//the same key even though they are separate instances in memory
myMap.getCount(); // 1
myMap.get(instance1) // "value2"
myMap.get(instance2) // "value2"
bugcore is dependent upon the bugpack framework

Instead use the Class.extend method and extend Obj. By using this method, it will exclude many of the base methods that the rest of the bugcore system depends upon, including hashCode, equals, _internalId, and clone

Method
/**

*/
_constructor: function() {
Parameters
Examples
var myObj = new Obj();
Method
/**
* @return {number}
*/
getInternalId: function() {
Parameters
Returns
{number} - The unique internal id for this instance. Unique only to this JS runtime.Examples
var myObj = new Obj();
var internalId = myObj.getInternalId();
By default the clone method will use the instance's Class to instantiate a new instance. It will also iterate through the instance's properties and attempt to clone all properties that are not functions. If a deep clone is being performed, then the clone method will attempt to create a deep copy of each property. If a shallow clone is being performed then a reference to the property value will be set on the new instance.
Notes
Method
/**
* @param {boolean=} deep
* @return {*}
*/
clone: function(deep) {
Parameters
| Name | Type | Description |
|---|---|---|
deep | {boolean=} | Whether or not to perform a deep clone. Optional - default: false |
Returns
{*} - A clone of the instance.Examples
var myObj = new Obj();
var shallowCloneObj = myObj.clone(); //shallow clone
var deepCloneObj = myObj.clone(true); //deep clone
By default, the equality check will compare this instances _internalId to the value parameter.
Notes
Method
/**
* @param {*} value
* @return {boolean}
*/
equals: function(value) {
Parameters
| Name | Type | Description |
|---|---|---|
value | {*} | The value to compare to for equality. |
Returns
{boolean} - Whether or not the instance is equal to the value parameter.Examples
Two different instances are not equal
var obj1 = new Obj();
var obj2 = new Obj();
obj1.equals(obj2); //false
An instance is equal to itself
var obj1 = new Obj();
obj1.equals(obj1); //true
Clones are not equal unless the 'equals' method is overridden
var obj = new Obj();
var objClone = obj.clone();
obj.equals(objClone); //false
var obj = new Obj();
var objClone = obj.clone(true);
obj.equals(objClone); //false
Returns the objects hashCode. The generation of the hashCode is only run once and then cached.
Notes
Method
/**
* @return {number}
*/
hashCode: function() {
Parameters
Returns
{number} - The hash code of this instance.Examples
Get hash code of instance
var obj = new Obj();
var hashCode = obj.hashCode();
Clones the value parameter.
If the value implements IClone the clone() method will be called to perform a clone of the value. If the value is a basic value such as a number or string it will simply be passed through.
Method
/**
* @static
* @param {A} value
* @param {boolean=} deep
* @return {A}
* @template A
*/
Obj.clone = function(value, deep) {
Notes
Parameters
| Name | Type | Description |
|---|---|---|
value | {A} | The value to clone. |
deep | {boolean=} | Whether or not to perform a deep clone. Optional - default: false |

Checks value1 and value2 for equality.
If value1 implements IEquals, the value1.equals() method will be used to perform the equality check. Otherwise === is used to compare the two values.

*/
Obj.equals = function(value1, value2) {
Parameters
| Name | Type | Description |
|---|---|---|
value1 | {*} | The value to compare value2 to for equality. |
value2 | {*} | The value to compare value1 to for equality. |
Returns
{boolean} - Whether or not the two values are equal.Examples
Two different instances are not equal
var obj1 = new Obj();
var obj2 = new Obj();
Obj.equals(obj1, obj2); //false
An instance is equal to itself
var obj1 = new Obj();
Obj.equals(obj1, obj1); //true
Strings of the same value are equal
var string1 = "mystring";
var string2 = "mystring";
Obj.equals(string1, string2) //true
Undefined and null are not equal
var undefinedValue = undefined;
var nullValue = null;
Obj.equals(undefinedValue, nullValue) //false
Two Dates of the same time are equal
var time = Date.now();
var date1 = new Date(time);
