How to use

Pass in an object that is key/function pairs. Reimplement will then run the function in the key/function(initializer) pair passing in the previous function(previousMethod). The initializer function should return a function(newMethod) that uses the previousMethod however it wants.

Syntax

myClass.reimplement({
    someExistingMethod: function(original){
        return function() {
            //do something before
            original();
            //do something after
        }
    }
});

Example

var P = new Class({
        initialize: function() {
                console.log('initializing');
        },
        doStuff: function(){
                console.log('doing stuff!');
        }
});

var a = new P();
a.doStuff();


P.reimplement({

        doStuff: function(func){
                return function(){
                        console.log('before doing stuff');
                        func();
                        console.log('after doing stuff');
                };
        }

});

a.doStuff();
