/**
* ApplicationAdapter class serves as a base class for your Red5 applications.
* It provides methods to work with SharedObjects and streams, as well as
* connections and scheduling services.
* ApplicationAdapter is an application level IScope. To handle streaming
* processes in your application you should implement
* {@link IStreamAwareScopeHandler} interface and implement handling methods.
*
* Application adapter provides you with useful event handlers that can be used
* to intercept streams, authorize users, etc. Also, all methods added in
* subclasses can be called from client side with NetConnection.call method.
* Unlike to Flash Media server which requires you to keep methods on Client
* object at server side, Red5 offers much more convenient way to add methods
*
* EXAMPLE:
*
*
* public List<String> getLiveStreams() {
* // Implementation goes here, say, use Red5 object to obtain scope and all it's streams
* }
*
*
*
* This method added to ApplicationAdapter subclass can be called from client
* side with the following code:
*
*
* var nc:NetConnection = new NetConnection();
* nc.connect(...);
* nc.call("getLiveStreams", resultHandlerObj);
*
*
*
* If you want to build a server-side framework this is a place to start and
* wrap it around ApplicationAdapter subclass.
