Examples of org.eclipse.jgit.dircache.DirCacheEntry

org.eclipse.jgit.dircache.DirCacheEntry
A single file (or stage of a file) in a {@link DirCache}.
An entry represents exactly one stage of a file. If a file path is unmerged then multiple DirCacheEntry instances may appear for the same path name.
