Examples of EntityManagerFactory

javax.persistence.EntityManagerFactory
Interface used to interact with the entity manager factory for the persistence unit.
When the application has finished using the entity manager factory, and/or at application shutdown, the application should close the entity manager factory. Once an EntityManagerFactory has been closed, all its entity managers are considered to be in the closed state. @since Java Persistence 1.0
