public abstract class ChangeNotesState
extends Object

Immutable state associated with a change meta ref at a given commit.

One instance is the output of a single ChangeNotesParser, and contains types required to support public methods on ChangeNotes. It is intended to be cached in-process.

Note that ChangeNotes contains more than just a single ChangeNoteState, such as per-draft information, so that class is not cached directly.
