Class TwoPhaseCoordinator

  • All Implemented Interfaces:
    Reapable
    Direct Known Subclasses:
    AtomicAction
    public class TwoPhaseCoordinator
extends BasicAction
implements Reapable
    Adds support for synchronizations to BasicAction. It does not change thread associations either. It also allows any thread to terminate a transaction, even if it is not the transaction that is marked as current for the thread (unlike the BasicAction default).
    Since:
    JTS 3.0.

      • cancel

        public int cancel()
        If this method is called and a transaction is not in a status of RUNNING, ABORT_ONLY or COMMITTING then do not call afterCompletion. A scenario where this may occur is if during the completion of a previous transaction, a runtime exception is thrown from one of the AbstractRecords methods. RuntimeExceptions are not part of the contract of the API and as such all we can do is leave the transaction alone.
