public final class DiffNode
- extends PathNode
A diffnode in a diffpath.
A DiffNode and its previous node mark a delta between two input sequences, that is, two differing
subsequences between (possibly zero length) matching sequences.
Snakes allow for compression of diffpaths, as each
snake is represented by a single

insertions and deletions is represented by a single
