Interface Transaction

public interface Transaction
The Transaction interface allows operations to be performed against the transaction in the target Transaction object. A Transaction object is created corresponding to each global transaction creation. The Transaction object can be used for resource enlistment, synchronization registration, transaction completion, and status query operations.

    • commit

      void commit() throws RollbackException, HeuristicMixedException, HeuristicRollbackException, SecurityException, IllegalStateException, SystemException
      Complete the transaction represented by this Transaction object.
      Throws:
      RollbackException - Thrown to indicate that the transaction has been rolled back rather than committed.
      HeuristicMixedException - Thrown to indicate that a heuristic decision was made and that some relevant updates have been committed while others have been rolled back.
      HeuristicRollbackException - Thrown to indicate that a heuristic decision was made and that all relevant updates have been rolled back.
      SecurityException - Thrown to indicate that the thread is not allowed to commit the transaction.
      IllegalStateException - Thrown if the transaction in the target object is inactive.
      SystemException - Thrown if the transaction manager encounters an unexpected error condition.

    • delistResource

      boolean delistResource(XAResource xaRes, int flag) throws IllegalStateException, SystemException
      Disassociate the resource specified from the transaction associated with the target Transaction object.
      Parameters:
      xaRes - The XAResource object associated with the resource (connection).
      flag - One of the values of TMSUCCESS, TMSUSPEND, or TMFAIL.
      Returns:
      true if the resource was delisted successfully; otherwise false.
      Throws:
      IllegalStateException - Thrown if the transaction in the target object is inactive.
      SystemException - Thrown if the transaction manager encounters an unexpected error condition.

    • enlistResource

      boolean enlistResource(XAResource xaRes) throws RollbackException, IllegalStateException, SystemException
      Enlist the resource specified with the transaction associated with the target Transaction object.
      Parameters:
      xaRes - The XAResource object associated with the resource (connection).
      Returns:
      true if the resource was enlisted successfully; otherwise false.
      Throws:
      RollbackException - Thrown to indicate that the transaction has been marked for rollback only.
      IllegalStateException - Thrown if the transaction in the target object is in the prepared state or the transaction is inactive.
      SystemException - Thrown if the transaction manager encounters an unexpected error condition.

    • getStatus

      int getStatus() throws SystemException
      Obtain the status of the transaction associated with the target Transaction object.
      Returns:
      The transaction status. If no transaction is associated with the target object, this method returns the Status.NoTransaction value.
      Throws:
      SystemException - Thrown if the transaction manager encounters an unexpected error condition.

    • registerSynchronization

      void registerSynchronization(Synchronization sync) throws RollbackException, IllegalStateException, SystemException
      Register a synchronization object for the transaction currently associated with the target object. The transction manager invokes the beforeCompletion method prior to starting the two-phase transaction commit process. After the transaction is completed, the transaction manager invokes the afterCompletion method.
      Parameters:
      sync - The Synchronization object for the transaction associated with the target object.
      Throws:
      RollbackException - Thrown to indicate that the transaction has been marked for rollback only.
      IllegalStateException - Thrown if the transaction in the target object is in the prepared state or the transaction is inactive.
      SystemException - Thrown if the transaction manager encounters an unexpected error condition.

    • rollback

      void rollback() throws IllegalStateException, SystemException
      Rollback the transaction represented by this Transaction object.
      Throws:
      IllegalStateException - Thrown if the transaction in the target object is in the prepared state or the transaction is inactive.
      SystemException - Thrown if the transaction manager encounters an unexpected error condition.

    • setRollbackOnly

      void setRollbackOnly() throws IllegalStateException, SystemException
      Modify the transaction associated with the target object such that the only possible outcome of the transaction is to roll back the transaction.
      Throws:
      IllegalStateException - Thrown if the target object is not associated with any transaction.
      SystemException - Thrown if the transaction manager encounters an unexpected error condition.
