The car will re-engage the cruise control once the clutch is released, provided the computer doesn't sense an over-rev. I'm pretty sure this is in the manual. There's no problem with shifting when the cruise control is engaged as long as you don't go from 6th to 2nd or something along those lines of ridiculousness.
As for what the cruise control uses to operate, our cars are drive-by-wire and assuming everything else (which is probably the case) is electrically controlled, then the cruise control modifies throttle input electronically.
