de.tsl2.nano.persistence.provider

Class NanoEntityManagerFactory

java.lang.Object

de.tsl2.nano.persistence.provider.NanoEntityManagerFactory

All Implemented Interfaces:

javax.persistence.EntityManagerFactory

public class NanoEntityManagerFactory
extends Object
implements javax.persistence.EntityManagerFactory

simplified base implementation of an EntityManagerFactory and an abstract EntityManager.

Please extend the classes NanoEntityManagerFactory.AbstractEntityManager, NanoEntityManagerFactory.AbstractQuery and implement the abstract methods to have a reduced jpa persistence provider. This reduced provider wont support Criterias etc.

Call setEntityManagerImpl(String) to provide your implementation to this factory class
Call createEntityManager(Map) to get a new specialized EntityManager. The property map has to contain the following specific entries:
1. EM_IMPLEMENTATION: pointing to your special EntityManager implementation
2. jdbc.url: database connection url
3. jdbc.user: database connection user
4. jdbc.passwd: database connection password
