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.

If the library is missing something you need, please let us know!

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(); // 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"

This method is used to declare a low level base class in the bugcore system. Most of the time you should not use this method to declare new classes unless you are sure of what you are doing. 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

/**
 * @static
 * @param {Object.<string, *>} declaration
 * @return {function(new:Constructor)}
 */
Class.declare = function(declaration) {

Parameters

Name | Type | Description --- | --- | --- declaration | {Object.<string, *>} | An object that declares the methods of the new class.

Returns

{function(new:Constructor)} - The newly created class's constructor.

Examples

var LowestLevelObject = Class.declare({
    _constructor: function() {
        // No need to call this._super, this is the lowest level.
    }
});

This method is used to determine if a value extends a particular Constructor's Class. Instances of Classes are considered to extend their own Class.

Method

/**
 * @static
 * @param {*} value
 * @param {function(new:Constructor)} constructor
 * @return {boolean}
 */
Class.doesExtend = function(value, constructor) {

Parameters

Name | Type | Description --- | --- | --- value | {*} | The value to determine if it extends the given Constructor's Class constructor | {function(new:Constructor)} | The Constructor used to check if the value extends it's Class

Returns

{boolean} - Whether or not the value extends the given Constructor's Class

Examples

var BaseBall = Class.extend(Ball, {});
var myBaseBall = new BaseBall();

Class.doesExtend(myBaseBall, Ball);         //true
Class.doesExtend(myBaseBall, BaseBall);     //true

This method is used to determine if a value implements a particular Implementable's Interface.

Method

/**
 * @static
 * @param {*} value
 * @param {function(new:Implementable)} implementable
 * @return {boolean}
 */
Class.doesImplement = function(value, implementable) {

Parameters

Name | Type | Description --- | --- | --- value | {*} | The value to determine if it implements the given Implementable's Interface constructor | {function(new:Constructor)} | The Constructor used to check if the value extends it's Class

Returns

{boolean} - Whether or not the value implements the given Implementable's Interface

Examples

var IBall   = Interface.declare({});
var Ball    = Class.declare({});
Class.implement(Ball, IBall);

var myBall  = new Ball();

Class.doesImplement(myBall, IBall);         //true

This method is used to extend another Class. It accepts the Class's Constructor as a parameter and the declaration for the new Class.

Notes

The declaration can include methods and default properties for the new Class.
If you're creating a low level Class, it is best practice to extend Obj

Method

/**
 * @static
 * @param {function(new:Constructor)} constructor
 * @param {Object.<string, *>} declaration
 * @return {function(new:Constructor)}
 */
Class.extend = function(constructor, declaration) {

Parameters

Name | Type | Description --- | --- | --- constructor | {function(new:Constructor)} | The constructor of the class to extend. declaration | {Object.<string, *>} | An object that declares the methods of the new class.

Returns

{function(new:Constructor)} - The newly created class's constructor.

Examples

var BaseBall = Class.extend(Ball, {

    _constructor: function(diameter) {
        this._super(); // Call super constructor
        this.diameter = diameter;
    }

    throwBall: function() {

    }
});

This method marks a Class as implementing an Interface. When calling this method it will add the Implementable's Interface to the Class's list of Interfaces. It will also validate that the given Class actually implements all of the methods of the Interface. If the Class does not this method will throw an Error.

Method

/**
 * @static
 * @param {function(new:Constructor)} constructor
 * @param {function(new:Implementable)} implementable
 */
Class.implement = function(constructor, implementable) {

Parameters

Name | Type | Description --- | --- | --- constructor | {function(new:Constructor)} | The Constructor of the Class to implement the Interface. implementable | {function(new:Implementable)} | The Implementable of the Interface to implement.

Returns

None

Examples

var IBall   = Interface.declare({
    throwBall: function() {}
});

var Ball    = Class.declare({
    throwBall: function() {
        // Implementation of method
    }
});

Class.implement(Ball, IBall);

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

/**
 * @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

If two instances are equal, they should return the same hash code.

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

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

/**
 * @return {number}
 */
hashCode: function() {

Parameters

None

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

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);         //shallow clone

var myObj               = new Obj();
var deepCloneObj        = Obj.clone(myObj, true);   //deep clone

var myString            = "abc123";
var cloneString         = Obj.clone(myString);      //"abc123"

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

/**
 * @static
 * @param {*} value1
 * @param {*} value2
 * @return {boolean}
 */
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);
var date2   = new Date(time);
Obj.equals(date1, date2)        //true

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

/**
 * @static
 * @param {*} value
 * @return {number}
 */
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);

IClone

The base interface for cloning. If your Class can be cloned, you should implement this interface.

Interface

/**
 * @interface
 */
var IClone = Interface.declare({

Method Summary

Access | Signature | Return Type --- | --- | --- public | clone({boolean=} deep) | {*}

This method returns a clone of the instance that implements this interface. Implementations should respect the deep clone flag.

Notes

Implementations should respect the deep flag.
Immutable values need not be cloned on a deep clone.

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.

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

/**
 * @interface
 */
var IEquals = Interface.declare({

Method Summary

Access | Signature | Return Type --- | --- | --- public | equals({*} value) | {boolean}

This method returns true if the instance that implements this interface is equal to the given value. Returns false if the given value does not equal the instance.

Notes

Implementations should handle any value passed in as a parameter.

Method

/**
 * @param {*} value
 * @return {boolean}
 */
equals: function(value) {}

Parameters

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

/**
 * @interface
 */
var IHashCode = Interface.declare({

Method Summary

Access | Signature | Return Type --- | --- | --- public | hashCode() | {number}

This method returns a hash code for the current instance.

Notes

Implementations should try to generate a relatively unique hash code for the given instance.
If two instances are equal, they should return the same hash code.

Method

/**
 * @return {number}
 */
hashCode: function() {}

Parameters

None

Returns

{number} - The hash code for the instance.

Throwable
