All Implemented Interfaces:
Serializable, Referenceable, ObjectFactory, RepositorySource

public class JpaSource
extends Object

This method may be called each time the configuration changes, allowing the source to update itself.

Specified by:
initialize in interface RepositorySource
Throws:
RepositorySourceException
See Also:
RepositorySource.initialize(org.jboss.dna.graph.connector.RepositoryContext)

getReference

public Reference getReference()

Specified by:
getReference in interface Referenceable
See Also:
Referenceable.getReference()

getObjectInstance

public Object getObjectInstance(Object obj,
                                Name name,
                                Context nameCtx,
                                Hashtable<?,?> environment)

Throws:
Exception

getConnection

public RepositoryConnection getConnection()
                                   throws RepositorySourceException
Get a connection from this source. Even though each RepositorySource need not be thread safe, this method should be safe to be called concurrently by multiple threads.

Specified by:
getConnection in interface RepositorySource
Returns:
a connection
Throws:
RepositorySourceException - if there is a problem obtaining a connection
See Also:
RepositorySource.getConnection()

close

public void close()
Signal this source that it is no longer needed and should begin the process of reclaiming or closing all resources that it has acquired. Because connections may still be in use, this method may not necessarily close all resources immediately.

This is a required method, and must be called when this source is no longer needed if one or more connections have been obtained since the previous call to this method.

Note that calling this method also does not preclude obtaining more connections after this method is called. If that happens, this source should simply reacquire any resources necessary to provide additional connections, and this method needs to be called once again.

Specified by:
close in interface RepositorySource
See Also:
RepositorySource.close()
