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.

This implements a priority in which keys are given values that will keep them in the same priority in which they priorities are requested. Nested structures (those in which a key is contained within another key) are preserved in such a way that child keys are after the parent and before the key after the parent.
