Interface PersistenceProvider

Method Detail

• createEntityManagerFactory

  EntityManagerFactory createEntityManagerFactory(String emName,
                                                  Map map)

  Called by Persistence 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

• createContainerEntityManagerFactory

  EntityManagerFactory createContainerEntityManagerFactory(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). These properties may include properties to control schema generation. 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

• generateSchema

  void generateSchema(PersistenceUnitInfo info,
                      Map map)

  Create database schemas and/or tables and/or create DDL scripts as determined by the supplied properties.

  Called by the container when schema generation is to occur as a separate phase from creation of the entity manager factory.

  Parameters:

  info - metadata for use by the persistence provider

  map - properties for schema generation; these may also include provider-specific properties

  Throws:

  PersistenceException - if insufficient or inconsistent configuration information is provided of if schema generation otherwise fails

  Since:

  Java Persistence 2.1

• generateSchema

  boolean generateSchema(String persistenceUnitName,
                         Map map)

  Create database schemas and/or tables and/or create DDL scripts as determined by the supplied properties.

  Called by the Persistence class when schema generation is to occur as a separate phase from creation of the entity manager factory.

  Parameters:

  persistenceUnitName - the name of the persistence unit

  map - properties for schema generation; these may also contain provider-specific properties. The value of these properties override any values that may have been configured elsewhere.

  Returns:

  true if schema was generated, otherwise false

  Throws:

  PersistenceException - if insufficient or inconsistent configuration information is provided or if schema generation otherwise fails

  Since:

  Java Persistence 2.1

• getProviderUtil

  ProviderUtil getProviderUtil()

  Return the utility interface implemented by the persistence provider.

  Returns:

  ProviderUtil interface
