What are the element in State Chart diagrams
What are the element in State Chart diagrams ?
State: Itfs a condition when following events occur:
bject satisfies a condition.
Or performs a action.
Or waits for a event to happen.
Composite State : It has one or more sub states.
Initial State: It represents a state before any event occurs.
Final State: Represents completion of an activity.
Transition : Shows the change of one state to other.
Transition Fork: Denotes beginning of parallel path activities.
Transition Join: Denotes merging of parallel path activities.
Decision: Indicates condition to move to different states.
Shallow History: Represents the state last visited. When a transition to the indicator
fires, an object resumes the state it last had at the same level as the history indicator. Deep history: A deep history allows you to return from whatever sub-state, whereas a shallow one only remembers the initial state of a composite state.
2-Element Constraint: It shows a constraint on two classes or associations. OR constraint: - It shows an OR constraint on two classes or associations.
