ORM Function enhancements

Multiple data source support impacts the following ORM functions:

Description

Returns the Hibernate session associated with the data source in the request. If ORM is not configured for this data source, it results in an exception. If data source is not specified, the Hibernate session of the default data source is returned.
Use this session object to call the APIs, which, otherwise, ColdFusion does not expose.
For information on session APIs, see: http://docs.jboss.org/hibernate/core/3.3/api/org/hibernate/Session.html

Function syntax

ormgetsession([datasource])

ORMCloseSession

Description

Closes the Hibernate session associated with the data source in the request. If you do not specify a data source, the Hibernate session associated with the default data source is closed.

Function syntax

ormcloseallsessions()

ORMCloseAllSessions

Description

Closes all Hibernate sessions in the request.

Function Syntax

ormcloseallsessions()

ORMFlush

Description

Flushes the Hibernate session associated with the data source in the request. ORMFlush flushes all pending CRUD operations in the request. Any changes made in the objects, in the current ORM session, are saved to the database. If you do not specify the data source, the Hibernate session associated with the default data source is flushed.

ORMClearSession

Description

Clears the Hibernate session associated with the given data source.The function clears the first level cache and removes the objects that are not yet saved to the database.If you do not specify the data source, the Hibernate session associated with the default data source is cleared.

Function syntax

Ormclearsession([datasource])

ORMGetSessionFactory

Description

Returns the Hibernate Session Factory object associated with the data source. Results in an error if ORM is not configured for this data source. If you do not specify the data source, the Hibernate session factory object associated with the default data source is returned.
