public class SessionListenerCollection
extends AbstractCollection

A collection which iterates over instances of all listeners defined in guacamole.properties. For each listener defined in guacamole.properties, a new instance is created and stored in this collection. The contents of this collection is stored within the HttpSession, and will be reused if available. Each listener is instantiated once per session. Listeners are singleton classes within the session, but not globally.
