All Known Implementing Classes:

HibernateAdapter

public interface JpaAdapter

Provides a way for individual JPA implementations to properly set their implementation-specific properties to accurately map the JpaSource properties to the JPA implementation.

Method Summary

String	determineDialect(javax.persistence.EntityManager entityManager) Determines the dialect in an implementation-specific manager
javax.persistence.EntityManagerFactory	getEntityManagerFactory(JpaSource source) Returns an EntityManagerFactory based on the values in the given source.
Properties	getProperties(JpaSource source) Maps the JpaSource properties to the corresponding properties in the JPA implementation

Method Detail

getProperties

Properties getProperties(JpaSource source)

Maps the JpaSource properties to the corresponding properties in the JPA implementation

Parameters:

source - the JPA source to map; may not be null

Returns:

a map of properties that can be passed to Persistence.createEntityManagerFactory(String, Map); never null

determineDialect

String determineDialect(javax.persistence.EntityManager entityManager)

Determines the dialect in an implementation-specific manager

Parameters:

entityManager - an open and valid EntityManager; may not be null

Returns:

a string describing the dialect that will be used to set the dialect property on the source; null indicates that the dialect could not be determined

getEntityManagerFactory

javax.persistence.EntityManagerFactory getEntityManagerFactory(JpaSource source)

Returns an EntityManagerFactory based on the values in the given source.

Parameters:

source - the JpaSource to use as a source of settings; may not be null

Returns:

an entity manager factory built from the settings on the source; never null
