    • isRollingback

      public boolean isRollingback()

    • setRollback

      protected boolean setRollback()
      Called by the ProcedureExecutor to mark rollback execution.

      protected long[] getSubprocedureIds()

    • getSubproceduresStack

      protected List<Procedure<Env>> getSubproceduresStack()

    • getException

      protected ProcedureException getException()

    • acquire

      protected boolean acquire()
      Called by the ProcedureExecutor to mark the procedure step as running.

    • release

      protected void release()
      Called by the ProcedureExecutor to mark the procedure step as finished.

    • abort

      protected void abort()

    • addRollbackStep

      protected void addRollbackStep(Procedure<Env> proc)
      Called by the ProcedureExecutor after the procedure step is completed, to add the step to the rollback list (or procedure stack).

    • addSubProcedure

      protected void addSubProcedure(Procedure<Env> proc)

    • loadStack

      protected void loadStack(Procedure<Env> proc)
      Called on store load by the ProcedureExecutor to load part of the stack.

      Each procedure has its own stack-positions. Which means we have to write to the store only the Procedure we executed, and nothing else. On load we recreate the full stack by aggregating each procedure stack-positions.
