- Method Detail
  - compute
```
public final void compute()
```
    Description copied from class: CountedCompleter
    
    The main computation performed by this task.
    
    Specified by:
    
    compute in class CountedCompleter
  - compute2
```
protected abstract void compute2()
```
  - onExceptionalCompletion
```
public boolean onExceptionalCompletion(java.lang.Throwable ex,
                              CountedCompleter caller)
```
    Description copied from class: CountedCompleter
    
    Performs an action when method ForkJoinTask.completeExceptionally(java.lang.Throwable) is invoked or method CountedCompleter.compute() throws an exception, and this task has not otherwise already completed normally. On entry to this method, this task ForkJoinTask.isCompletedAbnormally(). The return value of this method controls further propagation: If true and this task has a completer, then this completer is also completed exceptionally. The default implementation of this method does nothing except return true.
    
    Overrides:
    
    onExceptionalCompletion in class CountedCompleter
    
    Parameters:
    ex - the exception
    caller - the task invoking this method (which may be this task itself).
    
    Returns:
    true if this exception should be propagated to this tasks completer, if one exists.
