Interface StatelessSession

All Superinterfaces:

AutoCloseable, Closeable, Serializable, SharedSessionContract

All Known Implementing Classes:

StatelessSessionImpl

public interface StatelessSession
extends SharedSessionContract, Closeable

A command-oriented API for performing bulk operations against a database.

A stateless session does not implement a first-level cache nor interact with any second-level cache, nor does it implement transactional write-behind or automatic dirty checking, nor do operations cascade to associated instances. Collections are ignored by a stateless session. Operations performed via a stateless session bypass Hibernate's event model and interceptors. Stateless sessions are vulnerable to data aliasing effects, due to the lack of a first-level cache.

For certain kinds of transactions, a stateless session may perform slightly faster than a stateful session.

connection

@Deprecated
Connection connection()

Deprecated. just missed when deprecating same method from Session

Returns the current JDBC connection associated with this instance.

If the session is using aggressive connection release (as in a CMT environment), it is the application's responsibility to close the connection returned by this call. Otherwise, the application should not close the connection.

Returns:

The connection associated with this stateless session
