Creating state machines

You can create state machines to describe objects that have complicated or significant behavior. When you create a state machine, a single diagram and a region are created by default. A region is the container that holds the states and transitions that you add to the diagram to graphically describe the behavior of an object. You can create a state machine for classes, components, and operations.

Before you can add state machines to a model, you must have a UML modeling project open in the Modeling perspective.
To create a state machine:
  1. In the Model Explorer view, right-click a class, component, or operation; then click Add UML and complete one of the following steps.
    • To add a state machine to an operation, click State Machine Method
    • To add a state machine to a class or component, click State Machine
  2. Type a name for the state machine and press Enter.
