pack-priv Class RewriteGenerator

extends Generator
Class Inheritance
Imports
java.io.IOException, org.eclipse.jgit.errors.IncorrectObjectTypeException, .MissingObjectException
Replaces a RevCommit's parents until not colored with REWRITE.

Before a RevCommit is returned to the caller its parents are updated to create a dense DAG. Instead of reporting the actual parents as recorded when the commit was created the returned commit will reflect the next closest commit that matched the revision walker's filters.

This generator is the second phase of a path limited revision walk and assumes it is receiving RevCommits from TreeRevFilter.
