Abstract Class UML 2.5::LinkAction

Description:

LinkAction is an abstract class for all Actions that identify the links to be acted on using LinkEndData.

Direct Superclasses: Action

Direct Subclasses: WriteLinkAction, ReadLinkAction

Class Precedence List: LinkAction, Action, ExecutableNode, ActivityNode, RedefinableElement, NamedElement, Element

Properties:

endData : LinkEndData (2 *); -- source LinkAction
inputValue : InputPin (1 *); -- source LinkAction
context : Classifier (0 1); -- source Action

The context Classifier of the Behavior that contains this Action, or the Behavior itself if it has no context.
{readonly, derived}

input : InputPin (0 *); -- source Action
isLocallyReentrant : Boolean (1 1); -- source Action
localPostcondition : Constraint (0 *); -- source Action
localPrecondition : Constraint (0 *); -- source Action
output : OutputPin (0 *); -- source Action
handler : ExceptionHandler (0 *); -- source ExecutableNode
activity : Activity (0 1); -- source ActivityNode

inStructuredNode : StructuredActivityNode (0 1); -- source ActivityNode
incoming : ActivityEdge (0 *); -- source ActivityNode
outgoing : ActivityEdge (0 *); -- source ActivityNode
redefinedNode : ActivityNode (0 *); -- source ActivityNode

ActivityNodes from a generalization of the Activity containining this ActivityNode that are redefined by this ActivityNode.
Subsets: RedefinableElement.redefinedElement

Constraints:

No additional constraints.

Operations:

Signature: association() : Association;
Description: Returns the Association acted on by this LinkAction.
Expression: result = (endData->asSequence()->first().end.association)
