RootProcedureStack

public RootProcedureStack()

方法详细资料

isFailed

public boolean isFailed()

isRollingback

public boolean isRollingback()

setRollback

protected boolean setRollback()

Called by the ProcedureExecutor to mark rollback execution

unsetRollback

protected void unsetRollback()

Called by the ProcedureExecutor to mark rollback execution

getSubprocedureIds

protected long[] getSubprocedureIds()

getSubproceduresStack

protected java.util.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.
