Abstract Class UML 2.4.1::ActivityEdge

Description:

Activity edges can be contained in interruptible regions.An activity edge is an abstract class for directed connections between two activity nodes.

Direct Superclasses: RedefinableElement

Direct Subclasses: ObjectFlow, ControlFlow

Class Precedence List: ActivityEdge, RedefinableElement, NamedElement, Element
