virtual void Document::DocumentDelta::unapply ( Track::Track &  track  )  [pure virtual]

Reverse the action.

This will only be called when the track is in the same state having just called

 apply(track)
, and must take the track back to the state it was in before calling apply.
Parameters:
track The track to apply the changes to.
