Description

Interface Summary

BridgeMembershipEvent	An event delivered to a BridgeMembershipListener when this process detects connection changes to BridgeServers or bridge clients.
BridgeMembershipListener	A listener whose callback methods are invoked when this process detects connection changes to BridgeServers or bridge clients.
BridgeServer	A cache bridge server that serves the contents of a Cache to VMs in another distributed system via a socket.
Gateway	A Gateway represents a local proxy for a remote WAN (or distributed system).
Gateway.Endpoint	An Endpoint represents a proxy to a remote host
GatewayEvent	Interface GatewayEvent represents Cache events delivered to Gateways.
GatewayEventListener	Implementers of interface GatewayEventListener process batches of GatewayEvents.
GatewayHub	A GatewayHub manages a collection of Gateways.
ObjectSizer	The sizer interface defines a method that when called returns the size of the object passed in.

Class Summary

BoundedLinkedHashMap	Class BoundedLinkedHashMap is a bounded LinkedHashMap.
BridgeClient	This class combines the BridgeWriter and BridgeLoader functionality into one class, sharing BridgeServer connections, optimizing the number of connections required when using a BridgeWriter and BridgeLoader separately.
BridgeEventCallbackArgument	Class BridgeEventCallbackArgument is a wrapper on a callback arg plus the host and port of the client originating the event containing this BridgeEventCallbackArgument.
BridgeLoader	A CacheLoader that loads data from one or more remote cacheserver processes.
BridgeMembership	Provides utility methods for registering and unregistering BridgeMembershipListeners in this process.
BridgeMembershipListenerAdapter	Utility class that implements all methods in BridgeMembershipListener with empty implementations.
BridgeWriter	A CacheWriter that writes data to one or more remote CacheServer processes.
CacheListenerAdapter	Utility class that implements all methods in CacheListener with empty implementations.
CacheWriterAdapter	Utility class that implements all methods in CacheWriter with empty implementations.
CqListenerAdapter
GatewayEventCallbackArgument	Class GatewayEventCallbackArgument is a wrapper on a callback arg plus the id of the GatewayHub making the request.
GatewayQueueAttributes	Class GatewayQueueAttributes contains attributes related to the Gateway queue such as batch size and disk directories.
ObjectSizerImpl	This class provides an implementation of the ObjectSizer interface.
RegionMembershipListenerAdapter	Utility class that implements all methods in RegionMembershipListener with empty implementations.
RegionRoleListenerAdapter	Utility class that implements all methods in RegionRoleListener with empty implementations.
TransactionListenerAdapter	Utility class that implements all methods in TransactionListener with empty implementations.
UniversalMembershipListenerAdapter	The UniversalMembershipListenerAdapter is a wrapper for SystemMembershipListener and BridgeMembershipListener, providing a facade that makes both appear to customer code as a single SystemMembershipListener from the Admin API.
UniversalMembershipListenerAdapter.AdaptedMembershipEvent	Adapts BridgeMembershipEvent to look like a SystemMembershipEvent

Exception Summary

BridgeWriterException	An exception that is thrown by a BridgeWriter when a problem occurs when communicating with a bridge server.
ClientNotReadyException	A ClientNotReadyException indicates a client attempted to invoke the Cache.readyForEvents() method, but failed.
EndpointDoesNotExistException	An EndpointDoesNotExistException indicates a client Endpoint does not exist for the input name, host and port.
EndpointException	An EndpointException is a generic exception that indicates a client Endpoint exception has occurred.
EndpointExistsException	An EndpointExistsException indicates a client Endpoint already exists.
EndpointInUseException	An EndpointInUseException indicates a client Endpoint is in use (meaning that it contains one or more Connections.
ServerRefusedConnectionException	A ServerRefusedConnectionException indicates a client attempted to connect to a server, but the handshake was rejected.

Package com.gemstone.gemfire.cache.util Description

Provides utilities for use with the Caching API in the com.gemstone.gemfire.cache package.

Adapter classes are provided for convenience in implementing the CacheListener, RegionMembershipListener, RegionRoleListener, TransactionListener, and CacheWriter interfaces. These adapter classes simply implement the interfaces with empty methods so that subclasses only need implement the methods that are of interest.

Also provided are BridgeLoader/BridgeWriter/BridgeServer, which are used for Hierarchical Caching.
