Interface Summary

ClientSessionService	The client session service manages client sessions.
ClientSessionStatusListener	A listener that services may register with the ClientSessionService to receive notification of local client session status changes such as disconnection or relocation.
DataService	Provides facilities for services to manage access to shared, persistent objects.
IdentityRelocationListener	A service can register an IdentityRelocationListener to be notified when an identity is about to be relocated from the local node if it needs to perform any work in advance of the identity relocation.
Node	An abstraction for node information, used in conjunction with the WatchdogService and NodeListeners.
NodeListener	A listener that can be registered with the WatchdogService to be notified of node status events.
NodeMappingListener	A listener that can be registered with the NodeMappingService to be notified of identities being added to or removed from the local node.
NodeMappingService	The Node Mapping Service has the following responsibilities: maintain mapping of active identities to nodes, and vice versa decide when the mapping should change (e.g.
NonDurableTransactionParticipant	Defines a TransactionParticipant that does not maintain durable persistent state of its own, but instead relies on other participants to store any persistent state that it needs.
RecoveryListener	A service can register a RecoveryListener to be notified when that service on the local node needs to recover for the service on a failed node.
Service	This is the base interface used for all services.
SimpleCompletionHandler	A handler to be notified when operations for an associated request are complete.
TaskService	This Service provides facilities for scheduling tasks to run after the current task completes.
Transaction	This interface represents a single transaction.

TransactionParticipant	This interface is used by participants in transactions.
TransactionProxy	This is a proxy that provides access to the current transaction and its owner.
WatchdogService	The WatchdogService monitors the health of server nodes and notifies registered listeners of node status change events.
