org.compass.gps.device.jpa.lifecycle
Class HibernateJpaEntityLifecycleInjector

java.lang.Object
  org.compass.gps.device.jpa.lifecycle.HibernateJpaEntityLifecycleInjector

All Implemented Interfaces:

JpaEntityLifecycleInjector

Direct Known Subclasses:

HibernateJpaEntityCollectionLifecycleInjector

public class HibernateJpaEntityLifecycleInjector
extends Object
implements JpaEntityLifecycleInjector

Injects lifecycle listeners directly into Hibernate for mirroring operations.

By default, registers with plain insert/update/delete listeners, which will be triggered by Hibernate before committing (and up to Hibernate flushing logic). Also allows to be created with setting the registerPostCommitListeneres to true which will cause the insert/update/delete listeneres to be registered as post commit events.

Constructor Detail

HibernateJpaEntityLifecycleInjector

public HibernateJpaEntityLifecycleInjector()

HibernateJpaEntityLifecycleInjector

public HibernateJpaEntityLifecycleInjector(boolean registerPostCommitListeneres)

Creates a new lifecycle injector. Allows to control if the insert/update/delete even listeners will be registered with post commit listeres (flag it true) or with plain post events (triggered based on Hibrenate flushing logic).

Parameters:

registerPostCommitListeneres - true if post commit listeners will be registered. false for plain listeners.

Method Detail

requireRefresh

public boolean requireRefresh()

Description copied from interface: JpaEntityLifecycleInjector

Does this injector requires refreshing (i.e. remove and inject) of new listeners upon CompassGpsDevice.refresh().

Specified by:

requireRefresh in interface JpaEntityLifecycleInjector

injectLifecycle

public void injectLifecycle(javax.persistence.EntityManagerFactory entityManagerFactory,
                            JpaGpsDevice device)
                     throws JpaGpsDeviceException

Description copied from interface: JpaEntityLifecycleInjector

Injects a global lifecycle listener into the concrete EntityManagerFactory implementation.

Specified by:

injectLifecycle in interface JpaEntityLifecycleInjector

Parameters:

entityManagerFactory - The EntityManagerFactory to inject the global lifecycle to.

device - The Jpa device calling this injector

Throws:

JpaGpsDeviceException

removeLifecycle

public void removeLifecycle(javax.persistence.EntityManagerFactory entityManagerFactory,
                            JpaGpsDevice device)
                     throws JpaGpsDeviceException

Description copied from interface: JpaEntityLifecycleInjector

Removes (if possible) lifecycle listeners injected using the inject method.

Specified by:

removeLifecycle in interface JpaEntityLifecycleInjector

Parameters:

entityManagerFactory - The EMF to remove lifecycle from

device - The Jpa device calling

Throws:

JpaGpsDeviceException

doCreateListener

protected Object doCreateListener(JpaGpsDevice device)
