Method Summary

Modifier and Type	Method and Description
void	fulfillFinishedTaskStatus(Map<OperatorID,OperatorState> operatorStates) Fulfills the state for the finished subtasks and operators to indicate they are finished.
List<Execution>	getFinishedTasks() Returns tasks that have already been finished when taking the checkpoint.
Collection<ExecutionJobVertex>	getFullyFinishedJobVertex() Returns the job vertices whose tasks are all finished when taking the checkpoint.
List<ExecutionVertex>	getTasksToCommitTo() Returns tasks that are still running when taking the checkpoint, these need to be sent a message when the checkpoint is confirmed.
List<Execution>	getTasksToTrigger() Returns the tasks who need to be sent a message when a checkpoint is started.
List<Execution>	getTasksToWaitFor() Returns tasks who need to acknowledge a checkpoint before it succeeds.
boolean	mayHaveFinishedTasks() Returns whether we support checkpoints after some tasks finished.
void	reportTaskFinishedOnRestore(ExecutionVertex task) Reports the task is finished on restoring.
void	reportTaskHasFinishedOperators(ExecutionVertex task) Reports the task has finished all the operators.
