<BR> When called it performs three primary tasks: (1) Checks to see if rate direction has changed - if so calls the rateDirectionChanged method (2) Calls the transformMatrix method which the subclass defines (3) If doConstraintBoundsTesting is true does bounds testing of the target within the enclosing space and notifies of any collisions of the target with the space's sides.</TD></TR><TR
