bugcore
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!

written yet. If there are parts of the docs you'd like us to focus on, feel
free to ask!
Quick Examples
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();
}
});
Creation of a new class with overridden equals and hashCode methods
var SomeClassConstructor = Class.extend(Obj, {
_constructor: function(a, b) {
this._super();
this.a = a;
this.b = b
},
equals: function(value) {
if (Class.doesExtend(value, SomeClass)) {
return (Obj.equals(value.a, this.a) && Obj.equals(value.b, this.b));
}
return false;
},
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");
myMap.get("key2");
Use of a Map with instances as keys
var myMap = new bugcore.Map();
var instance1 = new SomeClass(123, "abc");
var instance2 = new SomeClass(123, "abc");
myMap.put(instance1, "value");
myMap.put(instance2, "value2");
myMap.getCount();
myMap.get(instance1)
myMap.get(instance2)

Obj#_constructor()
Method
_constructor: function() {
Parameters
Examples
var myObj = new Obj();
------------------------------------------------------------------------------------
Obj#getInternalId()
Method
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();
------------------------------------------------------------------------------------
### Obj#clone(deep)
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
- _internalId is not cloned for deep or shallow clones. Therefore the clone instance
is unique from that of the original.
Method
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();
var deepCloneObj = myObj.clone(true);
------------------------------------------------------------------------------------
### Obj#equals(value)
By default, the equality check will compare this instances _internalId to the value parameter.
Notes
- If two instances are equal, they should return the same hash code.
Method
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);
An instance is equal to itself
var obj1 = new Obj();
obj1.equals(obj1);
Clones are not equal unless the 'equals' method is overridden
var obj = new Obj();
var objClone = obj.clone();
obj.equals(objClone);
var obj = new Obj();
var objClone = obj.clone(true);
obj.equals(objClone);
------------------------------------------------------------------------------------
### Obj#hashCode()
Returns the objects hashCode. The generation of the hashCode is only run once and
then cached.
Notes
- If two instances are equal, they should return the same hash code.
- Equal hash codes is not a guarantee of equality.
- A hash code should not change for an instance over the lifespan of the instance.
- Generation of hash codes should be done only using immutable values.
Method
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();
------------------------------------------------------------------------------------
### Obj.clone(value, deep)
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
Obj.clone = function(value, deep) {
Notes
- If the value implements IClone, the clone() method will be used to clone the value.
- Cloning an object literal will create a new object literal and set references to all
iterable property values of the original object.
- Cloning a Date will create a new Date instance with the same time.
- Cloning an Array will create a new Array with the same values in the same order.
Parameters
Name | Type | Description |
---|
value | {A} | The value to clone. |
deep | {boolean=} | Whether or not to perform a deep clone. Optional - default: false |
Returns
{A}
- A clone of the value.
Examples
var myObj = new Obj();
var shallowCloneObj = Obj.clone(myObj);
var myObj = new Obj();
var deepCloneObj = Obj.clone(myObj, true);
var myString = "abc123";
var cloneString = Obj.clone(myString);
------------------------------------------------------------------------------------
### Obj.equals(value1, value2)
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.
Notes
- Two Date instances of the same time are considered equal
Method
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);
An instance is equal to itself
var obj1 = new Obj();
Obj.equals(obj1, obj1);
Strings of the same value are equal
var string1 = "mystring";
var string2 = "mystring";
Obj.equals(string1, string2)
Undefined and null are not equal
var undefinedValue = undefined;
var nullValue = null;
Obj.equals(undefinedValue, nullValue)
Two Dates of the same time are equal
var time = Date.now();
var date1 = new Date(time);
var date2 = new Date(time);
Obj.equals(date1, date2)
------------------------------------------------------------------------------------
### Obj.hashCode(value)
Returns the hashCode of the value. If the value implements IHashCode, then the
value.hashCode() method will be used to generate the hash code.
Method
Obj.hashCode = function(value) {
Parameters
Name | Type | Description |
---|
value | {*} | The value to generate a hash code for.. |
Returns
{number}
- The hash code of the value.
Examples
Get hash code of an instance.
var myObj = new Obj();
var hashCode = Obj.hashCode(myObj);
Get hash code of a string.
var myString = "abc123";
var hashCode = Obj.hashCode(myString);

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.
IEquals
The base interface for equality checks. If your Class can be compared for equality against
another, you should implement this interface.
Notes
- This interfaces must be implemented along with the the IHashCode interface if you want your
Class to work properly with the bugcore data classes.
- If two instances are equal, they should return the same hash code.
Interface
var IEquals = Interface.declare({
Method Summary
Access | Signature | Return Type |
---|
public | equals({*} value) | {boolean} |
------------------------------------------------------------------------------------
### IEquals#equals(value)

Name | Type | Description |
---|
value | {*} | The value to compare the instance against for equality. |
Returns
{boolean}
- Returns true if the instance is equal to the given value. False if not.
IHashCode
The base interface for generating a hash code for an instance. Used in tandem with the IEquals interface
for storing values in HashStore and HashTable.
Notes
- This interfaces must be implemented along with the the IEquals interface if you want your
Class to work properly with the bugcore data classes.
- If two instances are equal, they should return the same hash code.
- If two instances are not they can still return the same hash code. However, this should be avoided
to a degree as it will hurt the performance of HashTable and HashStore
- Equal hash codes does not guarantee equality.
Interface
var IHashCode = Interface.declare({
Method Summary
Access | Signature | Return Type |
---|
public | hashCode() | {number} |
------------------------------------------------------------------------------------
### IHashCode#hashCode()

]);
myCollection.containsEqual(["item1", "item2"]);
------------------------------------------------------------------------------------
### Collection#forEach(func)
forEach executes the provided function once for each element of the Collection.
Notes
- Order is not maintained in a Collection. Therefore the order of iteration in items in a
Collection is unpredictable.
- If a value is modified in one iteration and then visited at a later time, its value in
the loop is its value at that later time. A value that is deleted before it has been visited
will not be visited later. Values added to the Collection over which iteration is occurring
may either be visited or omitted from iteration. In general it is best not to add, modify or
remove values from the Collection during iteration, other than the value currently being
visited. There is no guarantee whether or not an added value will be visited, whether a
modified value (other than the current one) will be visited before or after it is modified,
or whether a deleted value will be visited before it is deleted.
Method
forEach: function(func) {
Parameters
Name | Type | Description |
---|
func | {function(I)} | The function to execute for each item |
Returns
Examples
Execute for each item
var myCollection = new Collection([
"item1",
"item2"
]);
myCollection.forEach(function(item) {
console.log(item);
});
Partial values contained are not a match.
var myCollection = new Collection([]);
myCollection.forEach(function(item) {
console.log(item);
});
------------------------------------------------------------------------------------
### Collection#getCount():number
Returns the number of items in the collection.
Method
getCount: function() {
Parameters
Returns
{number}
- The number of items in the Collection.
Examples
Empty Collection
var myCollection = new Collection([]);
myCollection.getCount();
Starts with 2 items
var myCollection = new Collection([
"item1",
"item2"
]);
myCollection.getCount()
------------------------------------------------------------------------------------
### Collection#getValueArray()
Returns an Array of the Collection's values.
Notes
- Order of items in the Array is unpredictable.
- This method generates a new Array each time.
- Manipulating the Array will not affect the Collection.
- Manipulating the Collection will not affect the returned Array after it has
been generated.
Method
getValueArray: function() {
Parameters
Returns
{
Array.<I>}
- An Array of the Collection's values.
Examples
Empty Collection
var myCollection = new Collection([]);
myCollection.getValueArray();
Starts with 2 items (order of items shown in examples is not indicative of real world results)
var myCollection = new Collection([
"item1",
"item2"
]);
myCollection.getValueArray()
Manipulation of Collection after array is returned.
(order of items shown in examples is not indicative of real world results)
var myCollection = new Collection([
"item1",
"item2"
]);
var myValueArray = myCollection.getValueArray();
myCollection.add("item3")
console.log(myCollection.getValueArray())
console.log(myValueArray)
------------------------------------------------------------------------------------
### Collection#getValueCount(value)
Returns an the number or items in the Collection that are equal to the given value.
Method
getValueCount: function(value) {
Parameters
Returns
{number}
- The number of items in the Collection that are equal to the given value.
Examples
var myCollection = new Collection([
"a",
"a",
"b"
]);
myCollection.getValueCount("a");
myCollection.getValueCount("b");
myCollection.getValueCount("c");
------------------------------------------------------------------------------------
### Collection#isEmpty()
Returns true if the Collection is empty.
Method
isEmpty: function() {
Parameters
Returns
{true}
- True if the Collection is empty.
Examples
Empty Collection
var myCollection = new Collection([]);
myCollection.isEmpty();
Not empty Collection
var myCollection = new Collection([
"a"
]);
myCollection.isEmpty();
------------------------------------------------------------------------------------
### Collection#iterator()
This method generates an iterator for this Collection.
Notes
- Because of the way javascript works and the current lack of Iterator support across browsers. Iterators
create a snap shot of the values in the Collection before starting the iteration process. If a value is modified
in one iteration and then visited at a later time, its value in the loop is its value when the iteration was
started.
- A value that is deleted before it has been visited WILL be visited later.
- Values added to the Collection over which iteration is occurring will be omitted from iteration.
- Iteration order of a Collection is not guaranteed.
Method
iterator: function() {
Parameters
Returns
Examples
Iterate Collection
var myCollection = new Collection([
"a",
"b",
"c"
]);
var iterator = myCollection.iterator();
while (iterator.hasNext()) {
var value = iterator.next();
}
Iterate past end of Collection
var myCollection = new Collection([
"a",
"b",
"c"
]);
var iterator = myCollection.iterator();
iterator.next();
iterator.next();
iterator.next();
iterator.next();

The root event class for all other events in the bugcore system.
Notes
- Events can be listened for by type and queried on by the data they contain
- Events bubble by default
Class
var Event = Class.extend(Obj, {
