Class UML 2.5::ProtocolTransition

Description:

A ProtocolTransition specifies a legal Transition for an Operation. Transitions of ProtocolStateMachines have the following information: a pre-condition (guard), a Trigger, and a post-condition. Every ProtocolTransition is associated with at most one BehavioralFeature belonging to the context Classifier of the ProtocolStateMachine.

Direct Superclasses: Transition

Direct Subclasses:

Class Precedence List: ProtocolTransition, Transition, Namespace, RedefinableElement, NamedElement, Element

Properties:

postCondition : Constraint (0 1); -- source ProtocolTransition

Specifies the post condition of the Transition which is the Condition that should be obtained once the Transition is triggered. This post condition is part of the post condition of the Operation connected to the Transition.
