Examples of org.tmatesoft.hg.repo.HgDataFile.workingCopy()

org.tmatesoft.hg.repo.HgDataFile.workingCopy()
Reads content of the file from working directory. If file present in the working directory, its actual content without any filters is supplied through the sink. If file does not exist in the working dir, this method provides content of a file as if it would be refreshed in the working copy, i.e. its corresponding revision (according to dirstate) is read from the repository, and filters repo -> working copy get applied. NOTE, if file is missing from the working directory and is not part of the dirstate (but otherwise legal repository file, e.g. from another branch), no content would be supplied. @param sink content consumer @throws CancelledException if execution of the operation was cancelled @throws HgRuntimeException subclass thereof to indicate issues with the library.
