Internal Transitions Hi,
When reading transitions out of a Statemachine-Diagram, is there a way to figure out if it is an internal transition or an self-transition? In both cases the target and the source of the transition is the same. Tanks! |

Re: Internal Transitions Hello,
As OMG's UML specification defines as below, Quote: An internal transition executes without exiting or re-entering the state in which it is defined. This is true even if the state machine is in a nested state within this state. An internal transitions allow execution of actions triggered by events without changing or leaving the state, and no entry and exit actions are dispatched. On the other hand, self-transitions always trigger and execute exit and entry actions. This is a subtle difference, though its the way to tell if it is an internal transition or self-transition.
