Adding transitions to states and pseudostates

In UML modeling, a transition is a relationship between two states in a state machine diagram. A series of states connected by transitions describes the various states of an object and the order in which each state is entered.

Before you can add a transition to a state or pseudostate, you must have a state machine diagram open in the Modeling perspective.
To add transitions to states and pseudostates:
  1. In the Palette, click Transition.
  2. Click and drag the source state and drag to the target state.
  3. Type a name for the transition and press Enter.
  4. In the Properties view, click the General tab.
  5. On the General page, in the Kind list, complete one of the following steps:
    • To specify that the transition does not enter or exit the source state when triggered, click Internal.
    • To specify that the transition does not exit the source composite state when triggered, click Local.
    • To specify that the transition will exit the source composite state when triggered, click External.
