Method Summary public  void addCurrent()      Create a new EntityManager on each PersistenceContext. public  void addExtraPersistenceUnitInfos(JPersistenceUnitInfo[] newPersistenceUnitInfos)      Adds new persistence unit infos to this persistence unit manager. Note: The persistence unit name have to be different from existing persistence units. public  void closeCurrentAndReturnToPrevious()      Sets back to the previous entity manager and close the current entity manager for each persistence context. public  EntityManager getEntityManager(String unitName, PersistenceContextType type)      Gets an entity manager for the given unit name and the extra attributes. public  EntityManagerFactory getEntityManagerFactory(String unitName)      Gets an entity manager factory for the given unit name. public  JPersistenceUnitInfo[] getPersistenceUnitInfos()      Gets the persistence unit infos used by this manager. public  void merge(EZBPersistenceUnitManager otherEZBPersistenceUnitManager)      Merge the persistence context of a an other persistent unit manager in this one. Constructor Detail PersistenceUnitManager public PersistenceUnitManager(JPersistenceUnitInfo[] persistenceUnitInfos)(Code) Build a new manager with given persistence units. Parameters:   persistenceUnitInfos - a list of persistence unit infos. Method Detail addCurrent public void addCurrent()(Code) Create a new EntityManager on each PersistenceContext. (Will be used for the method lifecycle) addExtraPersistenceUnitInfos public void addExtraPersistenceUnitInfos(JPersistenceUnitInfo[] newPersistenceUnitInfos)(Code) Adds new persistence unit infos to this persistence unit manager. Note: The persistence unit name have to be different from existing persistence units. Parameters:   newPersistenceUnitInfos - a list of persistence unit infos. closeCurrentAndReturnToPrevious public void closeCurrentAndReturnToPrevious()(Code) Sets back to the previous entity manager and close the current entity manager for each persistence context. getEntityManager public EntityManager getEntityManager(String unitName, PersistenceContextType type)(Code) Gets an entity manager for the given unit name and the extra attributes. Parameters:   unitName - the name of the persistence unit Parameters:   type - the type of the persistence context entity manager corresponding to arguments getEntityManagerFactory public EntityManagerFactory getEntityManagerFactory(String unitName)(Code) Gets an entity manager factory for the given unit name. Parameters:   unitName - the name of the persistence unit entity manager factory. getPersistenceUnitInfos public JPersistenceUnitInfo[] getPersistenceUnitInfos()(Code) Gets the persistence unit infos used by this manager. the persistence unit infos used by this manager. merge public void merge(EZBPersistenceUnitManager otherEZBPersistenceUnitManager)(Code) Merge the persistence context of a an other persistent unit manager in this one. Note that as specified in chapter 6.2.2 (persistence unit scope), an EAR level component level will only be seen by a subcomponent if it was not redefined. In our case : don't merge the given unit-name if the current manager defines this unit-name. Parameters:   otherEZBPersistenceUnitManager - the other persistence unit managerthat will be merged into this one.
