方法详细资料

isInputResettable

public boolean isInputResettable(int inputNum)

指定者:

isInputResettable 在接口中 ResettableDriver<org.apache.flink.api.common.functions.FlatJoinFunction<IT1,IT2,OT>,OT>

initialize

public void initialize()
                throws Exception

指定者:

initialize 在接口中 ResettableDriver<org.apache.flink.api.common.functions.FlatJoinFunction<IT1,IT2,OT>,OT>

抛出:

Exception

prepare

public void prepare()
             throws Exception

从接口复制的说明: Driver

This method is called before the user code is opened. An exception thrown by this method signals failure of the task.

指定者:

prepare 在接口中 Driver<org.apache.flink.api.common.functions.FlatJoinFunction<IT1,IT2,OT>,OT>

覆盖:

prepare 在类中 JoinDriver<IT1,IT2,OT>

抛出:

Exception - Exceptions may be forwarded and signal task failure.

run

public void run()
         throws Exception

从接口复制的说明: Driver

The main operation method of the task. It should call the user code with the data subsets until the input is depleted.

指定者:

run 在接口中 Driver<org.apache.flink.api.common.functions.FlatJoinFunction<IT1,IT2,OT>,OT>

覆盖:

run 在类中 JoinDriver<IT1,IT2,OT>

抛出:

Exception - Any exception thrown by this method signals task failure. Because exceptions in the user code typically signal situations where this instance in unable to proceed, exceptions from the user code should be forwarded.

cleanup

public void cleanup()
             throws Exception

从接口复制的说明: Driver

This method is invoked in any case (clean termination and exception) at the end of the tasks operation.

指定者:

cleanup 在接口中 Driver<org.apache.flink.api.common.functions.FlatJoinFunction<IT1,IT2,OT>,OT>

覆盖:

cleanup 在类中 JoinDriver<IT1,IT2,OT>

抛出:

Exception - Exceptions may be forwarded.

reset

public void reset()
           throws Exception

指定者:

reset 在接口中 ResettableDriver<org.apache.flink.api.common.functions.FlatJoinFunction<IT1,IT2,OT>,OT>

抛出:

Exception

teardown

public void teardown()

指定者:

teardown 在接口中 ResettableDriver<org.apache.flink.api.common.functions.FlatJoinFunction<IT1,IT2,OT>,OT>

cancel

public void cancel()

从接口复制的说明: Driver

This method is invoked when the driver must aborted in mid processing. It is invoked asynchronously by a different thread.

指定者:

cancel 在接口中 Driver<org.apache.flink.api.common.functions.FlatJoinFunction<IT1,IT2,OT>,OT>

覆盖:

cancel 在类中 JoinDriver<IT1,IT2,OT>
