Class RemoteCacheServer

java.lang.Object
  wt.cache.RemoteCacheServer

public class RemoteCacheServer

extends Object

Class that provides access to a remote cache server. Instances of this class are local (non-remote) objects that encapsulate the communication with a remote cache server object. This encapsulation includes object location, and automatic recovery from communication errors.

The local object represents the "concept" of a remote cache server, not a particular instance of the remote server that is bound to the local object. This allows the local object to manage connecting to a server object, and reconnecting to new server objects during error recovery.

This class is only used for communication from a slave cache to its master cache. The communication from a master to its registered slaves is handled in the CacheManager class because that communication does not share the same error recovery and server location policies.
