Method Summary

Methods

Modifier and Type	Method and Description
EntityManagerLiteFactory	createContainerEntityManagerFactory(javax.persistence.spi.PersistenceUnitInfo info, Map<?,?> map) Called by the container when an EntityManagerFactory is to be created.
EntityManagerLiteFactory	createEntityManagerFactory(String emName, Map<?,?> map) Called by PersistenceUnitAdmin class when an EntityManagerFactory is to be created.

Method Detail

createContainerEntityManagerFactory

EntityManagerLiteFactory createContainerEntityManagerFactory(javax.persistence.spi.PersistenceUnitInfo info,
                                                           Map<?,?> map)

Called by the container when an EntityManagerFactory is to be created.

Parameters:

info - metadata for use by the persistence provider

map - a Map of integration-level properties for use by the persistence provider (may be null if no properties are specified). If a Bean Validation provider is present in the classpath, the container must pass the ValidatorFactory instance in the map with the key "javax.persistence.validation.factory". If the containing archive is a bean archive, the container must pass the BeanManager instance in the map with the key "javax.persistence.bean.manager".

Returns:

EntityManagerFactory for the persistence unit specified by the metadata

createEntityManagerFactory

EntityManagerLiteFactory createEntityManagerFactory(String emName,
                                                  Map<?,?> map)

Called by PersistenceUnitAdmin class when an EntityManagerFactory is to be created.

Parameters:

emName - the name of the persistence unit

map - a Map of properties for use by the persistence provider. These properties may be used to override the values of the corresponding elements in the persistence.xml file or specify values for properties not specified in the persistence.xml (and may be null if no properties are specified).

Returns:

EntityManagerFactory for the persistence unit, or null if the provider is not the right provider
