JDO Interface

PersistenceManagerFactory

Super Interfaces:: Serializable

The PersistenceManagerFactory is the interface to use to obtain PersistenceManager instances. All PersistenceManager instances obtained from the same PersistenceManagerFactory will have the same default properties.

PersistenceManagerFactory instances may be configured and serialized for later use. They may be stored via JNDI and looked up and used later. Any properties configured will be saved and restored.

Once the first PersistenceManager is obtained from the PersistenceManagerFactory, the factory can no longer be configured.

If the ConnectionFactory property is set (non-null) then all other Connection properties including ConnectionFactoryName are ignored; otherwise, if ConnectionFactoryName is set (non-null) then all other Connection properties are ignored. Similarly, if the ConnectionFactory2 property is set (non-null) then ConnectionFactory2Name is ignored.

Operational state (PersistenceManager pooling, connection pooling, operational parameters) must not be serialized.

Public Methods

Add the FetchGroups to the set of active fetch groups.

FetchGroups are made unmodifiable before being added. FetchGroups that match existing FetchGroups replace the corresponding FetchGroups. The replaced FetchGroups become unscoped. Match is based on identical class and equal name. The methods addFetchGroups, removeFetchGroups, getFetchGroups, and removeAllFetchGroups are internally serialized.

Parameters:: groups - an array of FetchGroups

Throws:: SecurityExceptionif the caller is not authorized for {@link JDOPermission} ("manageMetadata")

Since:: JDO 2.2

Add the parameter listener to the list of instance lifecycle event listeners set as the initial listeners for each PersistenceManager created by this PersistenceManagerFactory.

The addInstanceLifecycleListener and removeInstanceLifecycleListener methods are considered to be configuration methods and can only be called when the PersistenceManagerFactory is configurable (before the first time getPersistenceManager is called).

The classes parameter identifies all of the classes of interest. If the classes parameter is specified as null, events for all persistent classes and interfaces will be sent to the listener.

The listener will be called for each event for which it implements the corresponding InstanceLifecycleListener interface.

Parameters:: listener - the lifecycle listener; classes - the classes of interest to the listener

Since:: JDO 2.0

Close this PersistenceManagerFactory.

Check for JDOPermission("closePersistenceManagerFactory") and if not authorized, throw SecurityException.

If the authorization check succeeds, check to see that all PersistenceManager instances obtained from this PersistenceManagerFactory have no active transactions. If any PersistenceManager instances have an active transaction, throw a JDOUserException, with one nested JDOUserException for each PersistenceManager with an active Transaction.

If there are no active transactions, then close all PersistenceManager instances obtained from this PersistenceManagerFactory, mark this PersistenceManagerFactory as closed, disallow getPersistenceManager methods, and allow all other get methods. If a set method or getPersistenceManager method is called after close, then JDOUserException is thrown.

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

Return:: a PersistenceManager instance with default options.

Since:: JDO 1.0

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

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

Return:: a PersistenceManager proxy.
