方法详细资料

getCheckpointBarrierHandler

protected Optional<CheckpointBarrierHandler> getCheckpointBarrierHandler()

从类复制的说明: StreamTask

Acquires the optional CheckpointBarrierHandler associated with this stream task. The CheckpointBarrierHandler should exist if the task has data inputs and requires to align the barriers.

覆盖:

getCheckpointBarrierHandler 在类中 StreamTask<OUT,TwoInputStreamOperator<IN1,IN2,OUT>>

createInputProcessor
