XALogger

private static class XALogger.XAReplayListener
extends Object
implements ReplayListener

private class used by XALogger.replay() methods. Used by replay(ReplayListener) and replay(ReplayListener, long) wrapper methods to intercept XACOMMIT and XACOMMITMOVED records so they can be passed to caller. During TM invoked replay, log records are returned to the caller, but the activeTx table is not updated.
