/** * VERSION: 1.24 * DATE: 2011-11-03 * AS3 * UPDATES AND DOCS AT: http://www.greensock.com/loadermax/ **/ package com.greensock.loading.data { import flash.display.DisplayObject; import flash.display.DisplayObjectContainer; /** * Can be used instead of a generic Object to define the vars parameter of a VideoLoader's constructor.

* * There are 2 primary benefits of using a VideoLoaderVars instance to define your VideoLoader variables: *
    *
  1. In most code editors, code hinting will be activated which helps remind you which special properties are available in VideoLoader
  2. *
  3. It enables strict data typing for improved debugging (ensuring, for example, that you don't define a Boolean value for onComplete where a Function is expected).
  4. *

* * The down side, of course, is that the code is more verbose and the VideoLoaderVars class adds slightly more kb to your swf. * * USAGE:

* Note that each method returns the VideoLoaderVars instance, so you can reduce the lines of code by method chaining (see example below).

* * Without VideoLoaderVars:
* new VideoLoader("video.flv", {name:"video", estimatedBytes:111500, container:this, width:200, height:100, onComplete:completeHandler, onProgress:progressHandler})

* * With VideoLoaderVars
* new VideoLoader("video.flv", new VideoLoaderVars().name("video").estimatedBytes(111500).container(this).width(200).height(100).onComplete(completeHandler).onProgress(progressHandler))
