    • getNumberOfInputs

      public int getNumberOfInputs()
      Description copied from interface: Driver
      Gets the number of inputs that the task has.
      Specified by:
      getNumberOfInputs in interface Driver<IT1,IT2>
      Returns:
      The number of inputs.

    • getStubType

      public Class<org.apache.flink.api.common.functions.FlatJoinFunction<IT1,IT2,OT>> getStubType()
      Description copied from interface: Driver
      Gets the class of the stub type that is run by this task. For example, a MapTask should return MapFunction.class.
      Specified by:
      getStubType in interface Driver<IT1,IT2>
      Returns:
      The class of the stub type run by the task.

    • getNumberOfDriverComparators

      public int getNumberOfDriverComparators()
      Description copied from interface: Driver
      Gets the number of comparators required for this driver.
      Specified by:
      getNumberOfDriverComparators in interface Driver<IT1,IT2>
      Returns:
      The number of comparators required for this driver.

    • isInputResettable

      public boolean isInputResettable(int inputNum)
      Specified by:
      isInputResettable in interface ResettableDriver<IT1,IT2>

    • initialize

      public void initialize()
      Specified by:
      initialize in interface ResettableDriver<IT1,IT2>

    • prepare

      public void prepare()
      Description copied from interface: Driver
      This method is called before the user code is opened. An exception thrown by this method signals failure of the task.
      Specified by:
      prepare in interface Driver<IT1,IT2>

    • run

      public void run() throws Exception
      Description copied from interface: Driver
      The main operation method of the task. It should call the user code with the data subsets until the input is depleted.
      Specified by:
      run in interface Driver<IT1,IT2>
      Throws:
      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()
      Description copied from interface: Driver
      This method is invoked in any case (clean termination and exception) at the end of the tasks operation.
      Specified by:
      cleanup in interface Driver<IT1,IT2>

    • reset

      public void reset()
      Specified by:
      reset in interface ResettableDriver<IT1,IT2>

    • teardown

      public void teardown()
      Specified by:
      teardown in interface ResettableDriver<IT1,IT2>

    • cancel

      public void cancel()
      Description copied from interface: Driver
      This method is invoked when the driver must aborted in mid processing. It is invoked asynchronously by a different thread.
      Specified by:
      cancel in interface Driver<IT1,IT2>
