Examples of org.red5.server.api.scope.IScopeHandler

org.red5.server.net.rtmp.event.IRTMPEvent
The scope handler controls actions performed against a scope object, and also is notified of all events. Gives fine grained control over what actions can be performed with the can methods. Allows for detailed reporting on what is happening within the scope with the on* methods. This is the core interface users implement to create applications. The thread local connection is always available via the Red5 object within these methods @author The Red5 Project @author Luke Hubbard (luke@codegent.com)
