Method Summary

Methods

Modifier and Type	Method and Description
void	close() Closes the repository (all acquired resources are released).

boolean	isClosed() Returns true if the repository is closed.

Method Detail

executeUnitOfWork

<T> T executeUnitOfWork(UnitOfWork<T> work)

Executes the given UnitOfWork within a single transaction.

Notes:

• If you need more fine grained transaction management, you can do so by manipulating currentSession() accordingly.
• Implementations of this class can be expected to be thread save; executing multiple units of work concurrently is save.
• It is not an error to execute a UnitOfWork while another UnitOfWork is already executing. However note that when doing so the Session or the current Transaction is not modified.

Specified by:

executeUnitOfWork in interface UnitOfWorkExecutor

Parameters:

work - a UnitOfWork that should be executed.

Returns:

the result of the UnitOfWork.

Throws:

ExecutionError - if UnitOfWork.execute() throws an exception.

currentSession

org.hibernate.Session currentSession()

Returns the currently open session for this thread.

Throws:

IllegalStateException - if no UnitOfWork is currently executing in this thread.
