Question

I'm a novice Uml guy I want to know if it is possible to have multiple transitions outgoing from the initial state in a statechart diagram

Était-ce utile?

La solution

As per spec, you need a single initial state (solid circle) with a single transition pointing to the "real" starting state, i.e. the state your system is when it starts. If you feel you need several transitions to several starting states, then either:

  • You are missing an intermediary state, that could be quite trivial (e.g. "started")
  • You might consider using a choice node (diamond node) just after the initial state, but it is not usually a good practice.
