Transitions

A transition is a graphical object that, in most cases, links one object to another. One end of a transition is attached to a source object and the other end to a destination object. The source is where the transition begins and the destination is where the transition ends. A transition label describes the circumstances under which the system moves from one state to another. It is always the occurrence of some event that causes a transition to take place. In the diagram on page 2-10, the transition from StateA1 to StateA2 is labeled with the event transitionA1_A2 that triggers the transition to occur.

Consider again the automatic transmission system. clutch_engaged is the event required to trigger the transition from neutral to engaged.
