Constructor Detail

HibernateProvider

public HibernateProvider(TopiaConfiguration topiaConfiguration,
                 TopiaServiceSupport topiaServiceSupport,
                 TopiaHibernateSessionRegistry sessionRegistry,
                 Set<Class<? extends TopiaEntity>> entityClasses)

Method Detail

getHibernateConfiguration

public org.hibernate.cfg.Configuration getHibernateConfiguration()

Get the current Hibernate Configuration. The Configuration instance is lazy-initialized using the newHibernateConfiguration() method. The returned instance is always initialized and mapping are built.

Returns:

the Hibernate Configuration instance with built mappings.

newHibernateConfiguration

public org.hibernate.cfg.Configuration newHibernateConfiguration()

Creates a new Configuration instance. The instance is create but mappings are not built yet to avoid unwanted database access.

Returns:

a new Hibernate Configuration instance without built mappings.

getHibernateDialect

public static String getHibernateDialect(TopiaConfiguration topiaConfiguration)

guessHibernateDialect

public static String guessHibernateDialect(String jdbcConnectionUrl)

getStandardServiceRegistry

protected static org.hibernate.boot.registry.StandardServiceRegistry getStandardServiceRegistry(org.hibernate.SessionFactory sessionFactory)

Method to extract from the given Hibernate SessionFactory a working instance of StandardServiceRegistry

IMPORTANT : As much as possible, prefer using the getSessionFactoryServiceRegistry(org.hibernate.SessionFactory) mthod instead of the current one because the SessionFactoryServiceRegistry is a child of the StandardServiceRegistry

NB: This method is static to make sure it does not depend on the current instance

Parameters:

sessionFactory - the Hibernate's SessionFactory instance

Returns:

the StandardServiceRegistry instance used by the given SessionFactory

getSessionFactoryServiceRegistry

protected static org.hibernate.service.spi.SessionFactoryServiceRegistry getSessionFactoryServiceRegistry(org.hibernate.SessionFactory sessionFactory)

Method to extract from the given Hibernate SessionFactory a working instance of SessionFactoryServiceRegistry

IMPORTANT : If possible, prefer using this method instead of getStandardServiceRegistry(org.hibernate.SessionFactory) because the SessionFactoryServiceRegistry is a child of the StandardServiceRegistry

NB: This method is static to make sure it does not depend on the current instance

Parameters:

sessionFactory - the Hibernate's SessionFactory instance

Returns:

the SessionFactoryServiceRegistry instance used by the given SessionFactory

getHibernateService

public static <S extends org.hibernate.service.Service> S getHibernateService(org.hibernate.SessionFactory sessionFactory,
                                                              Class<S> serviceClass)

Method to get an Hibernate service instance from a given Hibernate SessionFactory

NB: This method is static to make sure it does not depend on the current instance

Parameters:

sessionFactory - the Hibernate's SessionFactory instance

serviceClass - the expected service class

Returns:

the found service instance

Throws:

org.hibernate.service.UnknownServiceException - Indicates the service was not known.
