Class EventServer

java.lang.Object
  dermi.EventServer

All Implemented Interfaces:

java.io.Serializable

Direct Known Subclasses:

DermiProxy, DermiRemoteInterceptorObject, DermiRemoteObject

public class EventServer
extends java.lang.Object
implements java.io.Serializable

This is an utility class for skeletons and stubs (both inherit from EventServer). It handles event service connections, disconnections, event dispatching, exception wrapping, and stub class requests. It is internally used by Dermi, so IT IS NOT AIMED FOR END USERS.
