Examples of javax.jdo.PersistenceManagerFactory

javax.jdo.PersistenceManagerFactory
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. @version 2.1
