State (UML State Machine)

State is the nodes of the state diagram.

• When a state is active, the object is in that state.
• All internal activities specified in the current state can be executed.
• An activity can consist of multiple actions.

Activity specifications:

• entry / Activity(...): executed when the object enters the state
• exit / Activity(...): executed when the object exits the state
• do / Activity(...): executed while the object remains in this state
