Method Detail

getApplicationScopedPersistenceContext

public PersistenceContext getApplicationScopedPersistenceContext()

Specified by:

getApplicationScopedPersistenceContext in interface PersistenceContextManager

Returns:

a PersistenceContext instance containing the Application Scoped EntityManager.

getCommandScopedPersistenceContext

public PersistenceContext getCommandScopedPersistenceContext()

Specified by:

getCommandScopedPersistenceContext in interface PersistenceContextManager

Returns:

a PersistenceContext instance containing the Command Scoped EntityManager.

beginCommandScopedEntityManager

public void beginCommandScopedEntityManager()

Description copied from interface: PersistenceContextManager

This method should be called at the beginning of a CommandExecutor.execute(org.kie.api.command.Command) method, when the given CommandService instance is responsible for handling persistence. See the SingleSessionCommandService class.

The first responsibility of this method is to make sure that the Command Scoped EntityManager (CSEM) joins the ongoing transaction.

When the CSEM is internally managed, this method is also responsible for creating a new CSEM for use during execution of the Command or operation being executed by the KieSession.

Specified by:

beginCommandScopedEntityManager in interface PersistenceContextManager

endCommandScopedEntityManager

public void endCommandScopedEntityManager()

Description copied from interface: PersistenceContextManager

This method should only called in the Synchronization.afterCompletion(int) method.

It is responsible for cleaning up the Command Scoped EntityManager (CSEM) instance, but only when the CSEM is an internal one, and not one supplied (and managed) by the user.

If the CSEM is (internally) managed, then this method will take the necessary actions in order to make sure that a new CSEM can be generated at the beginning of the next operation or command on the persistent KieSession.

if the CSEM is supplied (and managed) by the user, this method will do nothing with the CSEM.

Specified by:

endCommandScopedEntityManager in interface PersistenceContextManager

dispose

public void dispose()

Description copied from interface: PersistenceContextManager

Executes the necessary actions in order to clean up and dispose of the internal fields of this instance.

Specified by:

dispose in interface PersistenceContextManager

clearPersistenceContext

public void clearPersistenceContext()
