  - setup
```
public void setup(TaskContext<org.apache.flink.api.common.functions.CoGroupFunction<IT1,IT2,OT>,OT> context)
```
    Specified by:
    
    setup in interface Driver<IT1,IT2>
  - 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.CoGroupFunction<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
```

    Specified by:
    
    isInputResettable in interface ResettableDriver<IT1,IT2>
  - initialize
```
public void initialize()
                throws Exception
```
    Specified by:
    
    initialize in interface ResettableDriver<IT1,IT2>
    
    Throws:
    
    Exception
  - 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:

```
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.

  - 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>
