Class JpaEntitiesLocatorDetector

java.lang.Object
  org.compass.gps.device.jpa.entities.JpaEntitiesLocatorDetector

public abstract class JpaEntitiesLocatorDetector
extends Object

A JpaEntitiesLocator detector. Tries to check for the actual implementation of JPA EntityManagerFactory, and based on it, check if the current set of actual JPA implementations is one of compass supported ones (like Hibernate).

If no implementation is found for the native EntityManagerFactory implementation, uses the DefaultJpaEntitiesLocator.

Currently support the following JPA implementations: Hibernate, TopLink Essentials (Glassfish Persistence), OpenJPA.

Assumes that the EntityManagerFactory is the native one, since the NativeJpaExtractor of the JpaGpsDevice was used to extract it.
