Class BridgeEventCallbackArgument

java.lang.Object
  com.gemstone.gemfire.cache.util.BridgeEventCallbackArgument

All Implemented Interfaces:

DataSerializable, Serializable

public class BridgeEventCallbackArgument
extends Object
implements DataSerializable

Class BridgeEventCallbackArgument is a wrapper on a callback arg plus the host and port of the client originating the event containing this BridgeEventCallbackArgument. It is created by the server when it receives an update request from a client and used to determine the originator of the event by the CacheClientNotifier. The original callback argument is wrapped by this one and replaced in the event sent to CacheListener, CacheWriter and CacheLoader.
