Class UML 2.3::FinalState

Description:

A special kind of state signifying that the enclosing region is completed. If the enclosing region is directly contained in a state machine and all other regions in the state machine also are completed, then it means that the entire state machine is completed.

Direct Superclasses: State

Direct Subclasses:

Class Precedence List: FinalState, State, Namespace, RedefinableElement, Vertex, NamedElement, Element

Properties:

connection : ConnectionPointReference (0 *); -- source State
connectionPoint : Pseudostate (0 *); -- source State
deferrableTrigger : Trigger (0 *); -- source State
doActivity : Behavior (0 1); -- source State
entry : Behavior (0 1); -- source State

An optional behavior that is executed whenever this state is entered regardless of the transition taken to reach the state. If defined, entry actions are always executed to completion prior to any internal behavior or transitions performed within the state.

exit : Behavior (0 1); -- source State
isComposite : Boolean (1 1); -- source State
isOrthogonal : Boolean (1 1); -- source State
isSimple : Boolean (1 1); -- source State
isSubmachineState : Boolean (1 1); -- source State
redefinedState : State (0 1); -- source State
redefinitionContext : Classifier (1 1); -- source State
region : Region (0 *); -- source State
stateInvariant : Constraint (0 1); -- source State

Specifies conditions that are always true when this state is the current state. In protocol state machines, state invariants are additional conditions to the preconditions of the outgoing transitions, and to the postcondition of the incoming transitions.
