Class TwoPhaseCoordinator

java.lang.Object
  com.arjuna.ats.arjuna.StateManager
      com.arjuna.ats.arjuna.coordinator.BasicAction
          com.arjuna.ats.arjuna.coordinator.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.
