Abstract Class UML 2.3::LinkAction

Description:

LinkAction is an abstract class for all link actions that identify their links by the objects at the ends of the links and by the qualifiers at ends of the links.

Direct Superclasses: Action

Direct Subclasses: WriteLinkAction, ReadLinkAction

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

Constraints:

Signature: same_pins() : Boolean;
Description: The input pins of the action are the same as the pins of the link end data and insertion pins.
The OCL used here is not normative.
Editor's notes: Added endif.
Expression: self.input->asSet() = let ledpins : Set = self.endData->collect(value) in if self.oclIsKindOf(LinkEndCreationData) then ledpins->union(self.endData.oclAsType(LinkEndCreationData).insertAt) else ledpins endif
Original: self.input->asSet() = let ledpins : Set = self.endData->collect(value) in if self.oclIsKindOf(LinkEndCreationData) then ledpins->union(self.endData.oclAsType(LinkEndCreationData).insertAt) else ledpins

Signature: same_association() : Boolean;
Description: The association ends of the link end data must all be from the same association and include all and only the association ends of that association.
The OCL used here is not normative.
Editor's notes: Removed close paren somewhere here.
Expression: self.endData->collect(end) = self.association()->collect(connection)
Original: self.endData->collect(end) = self.association()->collect(connection))

Signature: not_static() : Boolean;
Description: The association ends of the link end data must not be static.
The OCL used here is not normative.
Editor's notes: forAll not forall...but other problems too. I'll try this.
Expression: self.endData->forAll(end.isStatic = false)
Original: self.endData->forall(end.oclIsKindOf(NavigableEnd) implies end.isStatic = #false

Operations:

Signature: association() : Association;
Description: The association operates on LinkAction. It returns the association of the action.
Expression: result = self.endData->asSequence().first().end.association
