Statechart Diagram |
A
statechart diagram shows a state machine, a behavior that
specifies the sequences of states that an object goes through during its
life in response to events, together with its responses and actions. |
Generally, you can use a state diagram to illustrate which states a business
worker or a business entity can have - the events that cause a transition from
one state to another; and the actions that result from a state change. A
statechart diagram often simplifies the validation of the class design.
For each state that an object of the class can enter, a diagram shows the
messages it can receive, the actions to be carried out, and the state the object
of the class will be in thereafter.
