Quick Start

var classified = require('classified');

//root definition
var RootClass = classified({
	//constants
	SOME_CONSTANT: 'foo',
	
	//public properties
	sampleProperty: 4.5,
	
	//protected properties
	_sampleProperty: 5.5,
	
	//private properties
	__sampleProperty: 6.5,
	
	//constructor
	___construct: function() {
		this.constructCalled = true;
	},
	
	//public methods
	sampleMethod: function() {
		return this._sampleMethod();
	},
	
	//protected methods
	_sampleMethod: function() {
		return this.__sampleMethod();
	},
	
	//private methods
	__sampleMethod: function() {
		return this.SOME_CONSTANT + this._sampleProperty;
	}
});

//child definition
//you can use object or function as the definition
var ChildClass = RootClass.extend(function() {
	//constants
	this.SOME_CONSTANT_2 = 'bar';
	
	//protected properties
	this._sampleProperty = 7.5;
	
	//public methods
	this.sampleMethod = function() {
		return this._sampleMethod();
	};
	
	//protected methods
	this._sampleMethod = function() {
		return this.___parent._sampleMethod();
	};
});

//instantiate child
var child = ChildClass.load();

//test it
console.log(child.sampleMethod()); //--> foo7.5

try {
	child._sampleMethod();
} catch(e) {
	console.log('Protected call did not work');
}

Features

• Public, Private, Protected
• Constants
• Inheritance
• Traits

• Circular Dependencies Ready
• Node asyncrounous protected and private support

• definition() - Returns the entire definition including the protected and private properties
• parents() - Returns direct parents of this definition
• get() - Returns the publically accessable class definition function
• load() - Returns class defined instantiation
• register(string) - saves a state of the definition which can be recalled in trait
• trait(string|function|object) - will setup the provided as a parent, if string will recall from registry

What's up with the underscores?

• _ - protected properties and methods
• __ - private properties and methods
• ___ - Magic placeholder (Waiting on harmony)

Node Async Support

Use ___freeze() and ___unfreeze() in Node for asyncronous patterns as in the example below.

classified(function() {
	this._protectedValue = 4;
	this.somethingToAsync = function() {
		this.___freeze();
		setTimeout(function() {
			this._protectedValue = 5;
			this.___unfreeze();
		}.bind(this), 10);
	};
});
