Class DgcClient

java.lang.Object

org.apache.river.jeri.internal.runtime.DgcClient

public final class DgcClient
extends Object

Jeri ERI client-side DGC implementation. This class specializes AbstractDgcClient to use net.jini.jeri.Endpoint for transport endpoints, net.jini.id.Uuid for object identifiers, and net.jini.jeri.BasicObjectEndpoint for live remote references. This class's DgcProxy implementation maps dirty and clean calls to remote invocations on the DgcServer remote interface, through a BasicInvocationHandler and a BasicObjectEndpoint with the DgcProxy's Endpoint and the well-known Uuid for the Jini ERI server-side DGC implementation remote object.
