Seems like everyone has student discount microsoft 2010 a custom version of the Delegate these days. Whether it’s to student discount microsoft 2010 proxy events or control scope, one thing is clear, the solutions and student discount microsoft 2010 problems are just as numerous as its applications. The question I haven’t figured out yet is; which is the best?

Scope Issues

Proxy Issues
Ok, how about this… inspired by the Delegate Class refined buy windows office 2010, in conjunction with MTASC compliant Class Delegate, here’s a version that is a bit more hidden but doesn’t pollute the student discount microsoft 2010 arguments in the end function while still maintaining the ability to student discount microsoft 2010 remove itself from event subscriptions. I don’t really understand the whole MTASC thing because I don’t use it, so any comments to why this is a better/worse way would be good.

The reference to student discount microsoft 2010 the subscription function can be found inside the event function using “arguments.callee.self”. This is useful when you are using event proxies. If you don’t want to student discount microsoft 2010 access it in the proxied event then you should probably create a student discount microsoft 2010 variable for the delegate and subscribe/unsubscribe that way ( that’s another conversation - var f = Delegate.create( this, func) ).

Since it’s essentially storing another variable in the function, I’d be curious to run some performance tests. Here is the first version:

function create (s:Object, func:Function):Function
{
return function():Void{ func.apply(s, arguments); };
}

Here is the second version:

function create( obj:Object, func:Function ):Function
{
// SCOPED FUNCTION
// ______________________________
//
// dFunc = jgDelegate2.create ( this, o );
// dFunc ( ‘Hello World’ ); // Hello World
// ______________________________
//
// obj.addEventListener( ‘onEvent’, create ( listener, onEvent ) );
// obj.removeEventListener( ‘onEvent’, arguments.callee.self ); // onEvent var f = function ( )
{
var scope = arguments.callee.scope; // scope
var func = arguments.callee.func; // function
func.self = arguments.callee; // refernce for listeners return func.apply( scope, arguments); // method
}; f.scope = obj;
f.func = func;

return f;
}

Check it out with this example:

// create
var obj = {};
var listener = {};// initialize
mx.events.EventDispatcher.initialize ( obj );// listen
obj.addEventListener( ‘onEvent’, create ( listener, onEvent ) );// event
function onEvent ( eventObj:Object )
{
trace( eventObj.msg );
obj.removeEventListener( ‘onEvent’, arguments.callee.self ); // stop listening
}

// broadcast
var eventObj =
{
target:obj, // origin of event
type:“onEvent” , // event
msg:“Hello World” // additional properties
}
