Overview

This callback object implements the default set of callback events, which only returns the event itself. Note that #finished_a and #finished_b are not implemented – I haven’t yet figured out where they would be useful.

Note that this is intended to be called as is, e.g.,

Diff::LCS.LCS(seq1, seq2, Diff::LCS::DefaultCallbacks)
