public class PersistenceContextModel extends AbstractModel
Model support for persistence context elements.

Allocates a persistence context when this flow starts. The persistence context is closed when the flow ends. If the flow ends by reaching a "commit" end-state, changes made to managed persistent entities during the course of flow execution are flushed to the database in a transaction.

The persistence context can be referenced from within this flow by the "entityManager" variable.
