Field Detail

eventListeners

protected List eventListeners

EventListeners. Use a list to preserve ordering.

entityGraphListeners

protected List<JPAEntityGraphRegistrationListener> entityGraphListeners

Listeners for notification of when an EntityGraph is registered.

Constructor Detail

JPAMetaDataManager

public JPAMetaDataManager(org.datanucleus.NucleusContext ctxt)

Constructor.

Parameters:

ctxt - NucleusContext that this metadata manager operates in

Method Detail

registerEntityGraphListener

public void registerEntityGraphListener(JPAEntityGraphRegistrationListener listener)

registerEntityGraph

public void registerEntityGraph(JPAEntityGraph eg)

getEventListeners

public List getEventListeners()

Get the event listeners

Returns:

the event listeners

parseFile

protected org.datanucleus.metadata.FileMetaData parseFile(URL fileURL)

Utility to parse a file, using the "jpa" MetaData handler.

Specified by:

parseFile in class org.datanucleus.metadata.MetaDataManagerImpl

Parameters:

fileURL - URL of the file

Returns:

The FileMetaData for this file

postProcessClassMetaData

protected void postProcessClassMetaData(org.datanucleus.metadata.AbstractClassMetaData cmd,
                                        org.datanucleus.ClassLoaderResolver clr)

Method that will perform any necessary post-processing on metadata. In the case of JPA we need to populate all event listener methods against the listener.

Overrides:

postProcessClassMetaData in class org.datanucleus.metadata.MetaDataManagerImpl

Parameters:

cmd - Metadata for the class

clr - ClassLoader resolver

registerFile

public void registerFile(String fileURLString,
                         org.datanucleus.metadata.FileMetaData filemd,
                         org.datanucleus.ClassLoaderResolver clr)

Method to take the FileMetaData and register the relevant parts of it with the various convenience collections/maps that we use for access.

Specified by:

registerFile in interface org.datanucleus.metadata.MetaDataManager

Specified by:

registerFile in class org.datanucleus.metadata.MetaDataManagerImpl

Parameters:

fileURLString - URL of the metadata file

filemd - The File MetaData

getMetaDataForClassInternal

public org.datanucleus.metadata.AbstractClassMetaData getMetaDataForClassInternal(Class c,
                                                                                  org.datanucleus.ClassLoaderResolver clr)

Accessor for the JPA MetaData for a class. With JPA we either register the classes in "persistence.xml" (via "class", "jar-file" or "mapping-file") or we have them annotated. If they havent been loaded when we loaded "persistence.xml" then we only check for annotations in that class.

Specified by:

getMetaDataForClassInternal in interface org.datanucleus.metadata.MetaDataManager

Specified by:

getMetaDataForClassInternal in class org.datanucleus.metadata.MetaDataManagerImpl

Parameters:

c - The class to find MetaData for

Returns:

The ClassMetaData for this class (or null if not found)
