### Type Members

1. #### type Result = R

### Abstract Value Members

1. #### abstract def leaf(result: Option[R]): Unit

   Body of the task - non-divisible unit of work done by this task.

   Body of the task - non-divisible unit of work done by this task. Optionally is provided with the result from the previous completed task or `None` if there was no previous task (or the previous task is uncompleted or unknown).

2. #### abstract val result: R

   A result that can be accessed once the task is completed.

3. #### abstract def shouldSplitFurther: Boolean

   Decides whether or not this task should be split further.
