How to use

For new classes:

var someClass = new Class({
    Implements: [Guard]
});

For existing classes:

someClass.implement(Guard);

Adding a guard:

this.addGuard("someFunction", function(foo, bar){
    // do something, returning true to call the guarded function or false to cancel
});

Removing a guard:

this.removeGuard("someFunction");

By returning TRUE the function being guarded will be called, returning FALSE will result in it not being called.

You do not need to specify the parameters in the guard function unless you wish to validate against them.

Reference

addGuard(functionName, guardFunction);

this.addGuard("someFunction", function(foo, bar){
    // do something
});

addGuards(object);

this.addGuards({
    "someFunction": function(foo, bar){ 
        // do something
    },
    "anotherFunction": function(value){
        // do something
    }
});

removeGuard(functionName);

this.removeGuard("someFunction");

removeGuards(array);

this.removeGuard(["someFunction","anotherFunction"]);
