Mootools-Private

Private is a mutator which let you write code which use a sort of private properties and methods

How to use

Just include keeto.PatternMutator.js and kenta.Private.js, then you can write code like the snippet below:

var Test = new Class({
	Implements:[Options],
	'private initialize':function(options, _private){
		this.setOptions(options);
		_private.test = 'Hello, '+ (options.name || 'world!');
	},
	'private say':function(i_can_call_this_as_i_want){
		alert(i_can_call_this_as_i_want.test);
	},
	a_normal_method:function(){
		alert("I don't use privates");
	}
});

var kenta = new Test({name:'kenta'});
kenta.say();
kenta.a_normal_method();

var test2 = new Test({});
test2.say();

//when done
test2['~']();
kenta['~']();​

in order to access the private method/properties you must decorate the method name adding 'private' just before the method name.
