Method Detail

getPersistenceManager

JDOEntityManager getPersistenceManager()

Get an instance of JDOEntityManager from this factory. The instance has default values for options. This method overrides the getPersistenceManager method from PersistenceManagerFactory.

After the first use of getPersistenceManager, no "set" methods will succeed.

Specified by:

getPersistenceManager in interface PersistenceManagerFactory

Returns:

a JDOEntityManager instance with default options.

getPersistenceManagerProxy

JDOEntityManager getPersistenceManagerProxy()

Get a thread-safe instance of a proxy that dynamically binds on each method call to an instance of JDOEntityManager.

When used with a JDOEntityManagerFactory that uses TransactionType JTA, the proxy can be used in a server to dynamically bind to an instance from this factory associated with the thread's current transaction. In this case, the close method is ignored, as the PersistenceManager is automatically closed when the transaction completes.

When used with a JDOEntityManagerFactory that uses TransactionType RESOURCE_LOCAL, the proxy uses an inheritable ThreadLocal to bind to an instance of JDOEntityManager associated with the thread. In this case, the close method executed on the proxy closes the JDOEntityManager and then clears the ThreadLocal. Use of this method does not affect the configurability of the JDOEntityManagerFactory.

Specified by:

getPersistenceManagerProxy in interface PersistenceManagerFactory

Returns:

a PersistenceManager proxy.

2.1

getPersistenceManager

JDOEntityManager getPersistenceManager(java.lang.String userid,
                                       java.lang.String password)

Get an instance of JDOEntityManager from this factory. The instance has default values for options. The parameters userid and password are used when obtaining datastore connections from the connection pool.

After the first use of getPersistenceManager, no "set" methods will succeed.

Specified by:

getPersistenceManager in interface PersistenceManagerFactory

Parameters:

userid - the userid for the connection

password - the password for the connection

Returns:

a JDOEntityManager instance with default options.
