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

The connector direction, which can be set to one of:

  • Unspecified
  • Bi-Directional
  • Source -> Destination or
  • Destination -> Source

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

 Special Attributes

The x-coordinate of the connector's end point.

Connector end points are specified in Cartesian coordinates with the origin to the top left of the screen.

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

The properties are purposely undocumented because of their obscure nature and because they are subject to change as progressive enhancements are made to them.
