Examples of com.sun.sgs.service.TransactionListener

com.sun.sgs.service.TransactionListener
A listener to be notified before and after the completion of a transaction.
Callers can register {@code TransactionListener}s to learn about the completion of a transaction without joining the transaction as a {@link TransactionParticipant}. Because {@link Service}s may depend on operations performed by the {@link #beforeCompletion TransactionListener.beforeCompletion} methods of listeners that theyregister, {@code beforeCompletion} methods should not make calls to otherservices, even though the transaction is still considered active when {@code beforeCompletion} is called. The results of such calls are unspecified. @see Transaction#registerListener Transaction.registerListener

      /*
       * Don't use foreach iteration here, so that we can handle the
       * possibility that a beforeCompletion call adds another listener.
       */
      for (int i = 0; i < listeners.size(); i++) {
    TransactionListener listener = listeners.get(i);
    try {
        listener.beforeCompletion();
    } catch (RuntimeException e) {
        if (logger.isLoggable(Level.FINEST)) {
      logger.logThrow(
          Level.FINEST, e,
          "beforeCompletion {0} listener:{1} failed",
