public class JetspeedStateManagerService

extends BaseStateManagerService

JetspeedStateManagerService is an implementation of the BaseStateManagerService which manages the states stored in a local Map (synchronized HashMap).

Note: This implementation of the StateManagerService is independent of all other services; but it has no automatic way to retire no longer used state. If the application does not explicitly retire the states created, they will hang around forever. (see clear() and retireState() of the StateManagerService).
