bootstrapPersistenceContext

public PersistenceContext bootstrapPersistenceContext(java.lang.String name,
                                                      EntityManagerFactory emf,
                                                      java.net.URI baseURI,
                                                      java.lang.String version,
                                                      boolean replace)

Bootstrap a PersistenceContext based on an pre-existing EntityManagerFactory.

Parameters:

name - persistence context name

emf - entity manager factory

baseURI - base URI

version - JPARS version. See ServiceVersion for more details.

replace - Indicates that existing persistence context with given name and version must be replaced with the newly created one. If false passed the newly created context is not added to cache at all.

Returns:

newly created persistence context

close

public void close()

Stop the factory. Remove all the PersistenceContexts.

Specified by:

close in interface PersistenceContextFactory

closePersistenceContext

public void closePersistenceContext(java.lang.String name)

Close the PersistenceContext of a given name and clean it out of our list of PersistenceContexts.

Specified by:

closePersistenceContext in interface PersistenceContextFactory

Parameters:

name - name of the persistence context to close.

closePersistenceContext

public void closePersistenceContext(java.lang.String name,
                                    java.lang.String version)

Close the PersistenceContext and clean it out of our list of PersistenceContexts.

Parameters:

name - name of the persistence context to close.

version - persistence context version

createProperties

protected static java.util.Map<java.lang.String,java.lang.Object> createProperties(DynamicClassLoader dcl,
                                                                                   java.util.Map<java.lang.String,?> originalProperties)

Provide an initial set of properties for bootstrapping PersistenceContexts.

Parameters:

dcl -

originalProperties -

Returns:

get

public PersistenceContext get(java.lang.String persistenceUnitName,
                              java.net.URI defaultURI,

                              java.util.Map<java.lang.String,java.lang.Object> initializationProperties)

Gets existing persistence context or create new based on given parameters if it doesn't exist.

Specified by:

get in interface PersistenceContextFactory

getPersistenceContextNames

public java.util.Set<java.lang.String> getPersistenceContextNames()

Returns names of all currently cached persistence contexts.

Specified by:

getPersistenceContextNames in interface PersistenceContextFactory

getDynamicPersistenceContext

public PersistenceContext getDynamicPersistenceContext(java.lang.String name,
                                                       java.lang.String version)

Gets cached persistence context by its name and JPARS version.

Parameters:
