Field Detail

listeners

protected java.util.List listeners

EventListeners. Use a list to preserve ordering.

Constructor Detail

JPAMetaDataManager

public JPAMetaDataManager(org.datanucleus.OMFContext ctxt)

Constructor.

Parameters:

ctxt - ObjectManagerFactory Context that this metadata manager operates in

Method Detail

getListeners

public java.util.List getListeners()

Get the event listeners

Returns:

the event listeners

parseFile

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

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

Specified by:

parseFile in class org.datanucleus.metadata.MetaDataManager

Parameters:

fileURL - URL of the file

Returns:

The FileMetaData for this file

registerFile

public void registerFile(java.lang.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 class org.datanucleus.metadata.MetaDataManager

Parameters:

fileURLString - URL of the metadata file

filemd - The File MetaData

getMetaDataForClassInternal

public org.datanucleus.metadata.AbstractClassMetaData getMetaDataForClassInternal(java.lang.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 class org.datanucleus.metadata.MetaDataManager

Parameters:

c - The class to find MetaData for

Returns:

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