handleOperatorEvent

public void handleOperatorEvent(org.apache.flink.runtime.operators.coordination.OperatorEvent evt)

指定者:

handleOperatorEvent 在接口中 org.apache.flink.runtime.operators.coordination.OperatorEventHandler

close

public void close()
           throws Exception

从类复制的说明: AbstractStreamOperator

This method is called after all records have been added to the operators via the methods OneInputStreamOperator.processElement(StreamRecord), or TwoInputStreamOperator.processElement1(StreamRecord) and TwoInputStreamOperator.processElement2(StreamRecord).

The method is expected to flush all remaining buffered data. Exceptions during this flushing of buffered should be propagated, in order to cause the operation to be recognized asa failed, because the last data items are not processed properly.

指定者:

close 在接口中 StreamOperator<Object>

覆盖:

close 在类中 AbstractUdfStreamOperator<Object,SinkFunction<IN>>

抛出:

Exception - An exception in this method causes the operator to fail.

getOperatorIdFuture

public CompletableFuture<org.apache.flink.runtime.jobgraph.OperatorID> getOperatorIdFuture()
