System_CAPS_pubmethodShouldVisitRelationship(ElementWalker^, ModelElement^, DomainRoleInfo^, DomainRelationshipInfo^, ElementLink^)

Called to ask the filter if a particular relationship from a source element should be included in the traversal(Inherited from DslDefinitionModelDeleteClosureBase.)

System_CAPS_pubmethodShouldVisitRolePlayer(ElementWalker^, ModelElement^, ElementLink^, DomainRoleInfo^, ModelElement^)

This method is called to ask the filter if a particular role player associated with an ElementLink should be Visited during traversal. This overrides the generated ShouldVisitRolePlayer() method, which examines the PropagateDelete attribute on the ElementLink to decide whether to visit the associated role players. In this case the RelationshipPort, the shape drawn as a little square where a relationship is connected to a class, was not deleted with the relationship. The reason is that the link used to connect the RelationshipPort (a shape) to the RoleConnector (also a shape) is a subtype of ElementLink called LinkConnectsToNode. Instances of this link type are used to associate various NodeShapes with LinkShapes and so do not propagate deletes, although in the case of the RelationshipPort it should. The same problem existed for InheritancePort, which like RelationshipPort extends TogglePort. This method is called for every ElementLink visited during a delete. If the link in question is an instance of LinkConnectsToNode and the roleplayer is a TogglePort, then the port shape may not be needed anymore. By checking how many links are left to the target role player this method returns VisitorFilterResult.YES if there is exactly one link to the port, VisitorFilterResult.DoNotCare otherwise. This ensures that when the last link to the node is deleted the port shape is deleted as well.(Overrides DslDefinitionModelDeleteClosureBase::ShouldVisitRolePlayer(ElementWalker^, ModelElement^, ElementLink^, DomainRoleInfo^, ModelElement^).)
