Connector Class

To represent the various kinds of connectors between UML elements, you 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 to it a valid type from this 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

  • Unspecified

  • Bi-Directional

  • Source -> Destination or

  • Destination -> Source


If the connector is non-navigable, set the 'sourceNavigability' and/or 'targetNavigability' attributes. 		Special Attributes

String
Notes: Read Only
This low-level property returns an array providing information about the contents of the PData x fields.
These database fields are not documented and developers must gain understanding of these fields through their own endeavors to use this property.
MiscData is zero based, therefore:

  • MiscData(0) corresponds to PData1

  • MiscData(1) corresponds to PData2, and so on
