Connector Class
To represent the various kinds of connectors between UML elements, use a Connector object. You can access this from either the Client or Supplier element, using the Connectors collection of that element. When creating a new connector you assign it a valid type from the following list:
| • | Aggregation |
| • | Assembly |
| • | Association |
| • | Collaboration |
| • | CommunicationPath |
| • | Connector |
| • | ControlFlow |
| • | Delegate |
| • | Dependency |
| • | Deployment |
| • | ERLink |
| • | Generalization |
| • | InformationFlow |
| • | Instantiation |
| • | InterruptFlow |
| • | Manifest |
| • | Nesting |
| • | NoteLink |
| • | ObjectFlow |
| • | Package |
| • | Realization |
| • | Sequence |
| • | StateFlow |
| • | TemplateBinding |
| • | UseCase |
