Overview

This class is part of a private API. You should avoid using this class if possible, as it may be removed or be changed in the future.

Holds some metadata for tasks and stores the parent link for tasks. It separates some of the concerns between tasks and what they have to know to follow back up the chain.

All the methods here will simply delegate calls, either up to the parent, or down to the task.
