Annotation Type TransactionPolicy

@Retention(value=RUNTIME)
 @Target(value=METHOD)
public @interface TransactionPolicy

Annotates a ProgramLifecycle method to indicate that it will not run inside transaction. By default, program life cycle methods (initialize, destroy), are run inside a transaction. Some methods do not require a transaction, or they need to control their transactions themselves. Such a method can be annotated, for example in a worker, with:

  @Override
  @TransactionPolicy(TransactionControl.EXPLICIT)
 public void initialize(WorkerContext context) {
   ...
 }
 

This is especially useful if the method may run longer than the transaction timeout, and it would then fail if run inside a transaction.
