Examples of org.eclipse.jgit.revwalk.FollowFilter

org.eclipse.jgit.revwalk.FollowFilter
Updates the internal path filter to follow copy/renames.
This is a special filter that performs {@code AND(path, ANY_DIFF)}, but also triggers rename detection so that the path node is updated to include a prior file name as the RevWalk traverses history.
Results with this filter are unpredictable if the path being followed is a subdirectory.

    List<TreeFilter> followFilters = new ArrayList<TreeFilter>(paths.size());
    for (String path : paths)
      followFilters.add(createFollowFilter(path, diffConfig));


    if (followFilters.size() == 1) {
      FollowFilter followFilter = (FollowFilter) followFilters.get(0);
      renameTracker.reset(followFilter.getPath());
      return followFilters.get(0);
    }


    // TODO: this scenario is not supported by JGit: RewriteTreeFilter
