Annotation Type TransactionalLock

@Inherited
 @Retention(value=RUNTIME)
 @Target(value=METHOD)
public @interface TransactionalLock

The TransactionalLock annotation is used to provide advice around a joinpoint which will invoke a lock. The lock is invoked before the method begins and is released after it has executed.

This is mainly used in combination with Transactional methods to provide locking around the entire transaction in order to prevent other methods from performing work before a transaction has completed.
