Class EndpointListenerManager

java.lang.Object

org.gecko.rsa.topology.EndpointListenerManager

All Implemented Interfaces:

ServiceInterestListener

public class EndpointListenerManager
extends java.lang.Object
implements ServiceInterestListener

Manages the end-point listener for the import of external services. The end-point listener scope reflects the combined filters of all services that are asked for (by listeners and service lookups) in the current system. Discovery will then send callbacks when external end-points are added / removed that match the interest in the local system.
