AbstractPersistenceProvider

public AbstractPersistenceProvider()

Method Detail

setFlushModeManual

public abstract void setFlushModeManual(javax.persistence.EntityManager entityManager)

Set the flush mode to manual-only flushing. Called when an atomic persistence context is required.

isDirty

public abstract boolean isDirty(javax.persistence.EntityManager entityManager)

Does the persistence context have unflushed changes? If it does not, persistence context replication can be optimized.

Returns:

true to indicate that there are unflushed changes

getId

public Object getId(Object bean,
                    javax.persistence.EntityManager entityManager)

Get the value of the entity identifier attribute.

Parameters:

bean - a managed entity instance

getName

public String getName(Object bean,
                      javax.persistence.EntityManager entityManager)
               throws IllegalArgumentException

Get the name of the entity

Parameters:

bean -

entityManager -

Throws:

IllegalArgumentException - if the passed object is not an entity

getVersion

public Object getVersion(Object bean,
                         javax.persistence.EntityManager entityManager)

Get the value of the entity version attribute.

Parameters:

bean - a managed entity instance

checkVersion

public void checkVersion(Object bean,
                         javax.persistence.EntityManager entityManager,
                         Object oldVersion,
                         Object version)

enableFilter

public abstract void enableFilter(Filter filter,
                                  javax.persistence.EntityManager entityManager)

Enable a Filter. This is here just especially for Hibernate, since we well know that other products don't have such cool features.

registerSynchronization

public abstract boolean registerSynchronization(Synchronization sync,
                                                javax.persistence.EntityManager entityManager)

Register a Synchronization with the current transaction.

proxyDelegate

public Object proxyDelegate(Object delegate)

Wrap the delegate before returning it to the application

proxyEntityManager

public javax.persistence.EntityManager proxyEntityManager(javax.persistence.EntityManager entityManager)

Wrap the entityManager before returning it to the application

getBeanClass

public Class getBeanClass(Object bean)

Returns the class of an entity bean instance

Parameters:

bean - The entity bean instance

Returns:

The class of the entity bean

getPostLoadMethod

public Method getPostLoadMethod(Class beanClass,
                                javax.persistence.EntityManager entityManager)

getPrePersistMethod

public Method getPrePersistMethod(Class beanClass,
                                  javax.persistence.EntityManager entityManager)
