Examples of HgDataFile

org.tmatesoft.hg.repo.HgDataFile
Regular user data file stored in the repository.
Note, most methods accept index in the file's revision history, not that of changelog. Easy way to obtain changeset revision index from file's is to use {@link #getChangesetRevisionIndex(int)}. To obtain file's revision index for a given changeset, {@link HgManifest#getFileRevision(int,Path)} or {@link HgChangesetFileSneaker} may come handy. @author Artem Tikhomirov @author TMate Software Ltd.
