Interface PersistenceService

All Known Implementing Classes:

DatabasePersistenceService, FilePersistenceService, LazyPersistenceServiceDecorator, MemoryPersistenceService

public interface PersistenceService

This class defines the Persistence Service the config framework depends on.

The config framework provides a file-based implementation but new implementations - e.g. to memory, database, coherence - could be developped and used with the config framework.

Method Summary

Modifier and Type	Method and Description
void	disposeSession(java.lang.String session) callback to dispose a given session previously created but for which a persistence context has not been created.
java.util.Set<java.lang.String>	getSessions() returns the list of sessions that have been persisted.
void	initialize(ConfigService configService) callback to initialize the persistence service.
PersistenceContext	newContext(ConfigContext context, boolean isLoad) creates a new PersistenceContext for the given ConfigContext.

Method Detail

initialize

void initialize(ConfigService configService)
         throws java.lang.Exception

callback to initialize the persistence service. This is called during the config service start sequence.s

Throws:

java.lang.Exception

                                     throws java.lang.Exception

returns the list of sessions that have been persisted. This method is called primarily at initialization time to discover the sessions that had been persisted.

                              boolean isLoad)
                       throws java.lang.Exception

creates a new PersistenceContext for the given ConfigContext.

This method will be called during creation of the ConfigContext for the core state as well as any persisted sessions (load), and then for any newly created session.
