State machine (dictionary item)
For automation interface information about a State Machine, see
State Machine.
A State Machine defines a set of concepts that can be used for modeling discrete behavior through finite state-transition systems.
Create a State Machine through a Modeler explorer pane:
• Right-click a Model or Package, and select > > > .
• Right-click a Class, Interface, Operation or Subsystem, and select > .
Note that when you create a State Machine from a Class or Interface, Modeler also creates a State Diagram as a child of the new State Machine.
In addition, you can create a State Machine when creating a new Submachine State.
On State Diagrams, the owning State Machine is linked to the frame as follows.
The View Options on a State Diagram allow you to show or hide full name. By default, the full name is not shown.
