Examples of org.eclipse.jgit.treewalk.TreeWalk

org.eclipse.jgit.treewalk.TreeWalk
Walks one or more {@link AbstractTreeIterator}s in parallel.
This class can perform n-way differences across as many trees as necessary.
Each tree added must have the same root as existing trees in the walk.
A TreeWalk instance can only be used once to generate results. Running a second time requires creating a new TreeWalk instance, or invoking {@link #reset()} and adding new trees before starting again. Resetting anexisting instance may be faster for some applications as some internal buffers may be recycled.
TreeWalk instances are not thread-safe. Applications must either restrict usage of a TreeWalk instance to a single thread, or implement their own synchronization at a higher level.
Multiple simultaneous TreeWalk instances per {@link Repository} arepermitted, even from concurrent threads.
