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

从接口复制的说明: StreamOperator

This method is called at the very end of the operator's life, both in the case of a successful completion of the operation, and in the case of a failure and canceling.

This method is expected to make a thorough effort to release all resources that the operator has acquired.

NOTE:It can not emit any records! If you need to emit records at the end of processing, do so in the StreamOperator.finish() method.

指定者:

close 在接口中 StreamOperator<Object>

覆盖:

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

抛出:

Exception

getOperatorIdFuture

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