State Machine Diagram - State Notation
This section describes the State Notation used in a UML State Machine Diagram. A State Notation presents a situation during which the modeled object meets an invariant condition.
A State Notation is the primary graphical notation used in a UML State Machine Diagram to represent a situation during which the modeled object meets an invariant condition.
A State Notation is drawn as a rectangle shape with slightly rounded corners. State name is placed inside the rectangle. For example, "Locked" is a state of a "Door" object during which the "door is locked" invariant condition is always true. This state can be drawn as a State Notation in a UML State Machine diagram as shown below:
