  - isInputResettable
```
public boolean isInputResettable(int inputNum)

    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()
             throws Exception
```
    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>
    
    Overrides:
    
    prepare in class JoinDriver<IT1,IT2,OT>
    
    Throws:
    
    Exception - Exceptions may be forwarded and signal task failure.
  - 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>
    
    Overrides:
    
    run in class JoinDriver<IT1,IT2,OT>
    
    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()
             throws Exception
```
    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>
    
    Overrides:
    
    cleanup in class JoinDriver<IT1,IT2,OT>
    
    Throws:
    
    Exception - Exceptions may be forwarded.
  - reset
```
public void reset()
           throws Exception
```
    Specified by:
    
    reset in interface ResettableDriver<IT1,IT2>
    
    Throws:
    
    Exception
  - 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>
    
    Overrides:
    
    cancel in class JoinDriver<IT1,IT2,OT>
