If a type B firing has occurred and exactly one transition is enabled, then change state to the destination state of the enabled transition. Note that a type B firing is the last firing of an actor in an iteration of the HDF graph in which it is embedded. <p> If a state transition to a refinement with different port rates from the previous refinement occurs, then the port rates of the container of this director are updated to be consistant with the port rates of the new state's refinement. The HDF director will be notified of the change in port rates. If a change in port rates occurs and this FSM is governed by an SDF director, an exception will occur.
