Connector

public Class

A Connector object represents the various kinds of connectors between UML elements. It is accessed from either the Client or Supplier element, using the Connectors collection of that element. When creating a new connector you must 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
  • UseCase

Connector Attributes

Attribute

Type

Notes

Alias

String

Read/Write. An optional alias for this connector.

ClientEnd

ConnectorEnd

Read only. A pointer to the ConnectorEnd object representing the source end of the relationship.

ClientID

Long

Read/Write. ElementID of the element at the source end of this connector.

Color

Long

Read/Write. Sets the color of the connector.

ConnectorGUID

Variant

Read only. A globally unique ID for the current connector. System generated.

ConnectorID

Long

Read only. Local identifier for the current connector. System generated.

Constraints

Collection

Read only. Collection of constraint objects.

CustomProperties

Collection

Read only. Returns a collection of advanced properties associated with an element in the form of CustomProperty objects.

DiagramID

Long

Read/Write. The DiagramID of the connector.

Direction

String

Read/Write. Connector direction. Can be set to one of the following:

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

EndPointX

Long

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

Note:

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

EndPointY

Long

Read/Write. The y-coordinate of the connector's end point.

Note:

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

EventFlags

String

Read/Write. Structure to hold a variety of flags concerned with event signaling on messages.

IsLeaf

Boolean

Read/Write. Flag indicating connector is a leaf.

IsRoot

Boolean

Read/Write. Flag indicating connector is a root.

IsSpec

Boolean

Read/Write. Flag indicating connector is a specification.

MetaType

String

Read only. The connector's domain-specific meta type, as defined by an applied stereotype from an MDG Technology.

MiscData

String

Read only. This low-level property provides information about the contents of the PDatax 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) to PData2

and so on.

Name

String

Read/Write. The connector name.

Notes

String

Read/Write. Descriptive notes about the connector.

ObjectType

ObjectType

Read only. Distinguishes objects referenced through a Dispatch interface.

Properties

Properties

Returns a list of specialized properties that apply to the connector that might not be available using the automation model. The properties are purposely undocumented because of their obscure nature and because they are subject to change as progressive enhancements are made to them.

RouteStyle

Long

Read/Write. The route style.

SequenceNo

Long

Read/Write. The SequenceNo of the connector.

StartPointX

Long

Read/Write. The x-coordinate of the connector's start point.

Note:

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

StartPointY

Long

Read/Write. The y-coordinate of the connector's start point.

Note:

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

StateFlags

String

Read/Write. Structure to hold a variety of flags concerned with State signaling on messages, the  list delimited by semi-colons.

Stereotype

String

Read/Write. Sets or gets the stereotype for this connector end.

StereotypeEx

String

Read/Write. All the applied stereotypes of the connector in a comma-separated list.

StyleEx

String

Read/Write. Advanced style settings. Reserved for the use of Sparx Systems.

Subtype

String

Read/Write. A possible subtype to refine the meaning of the connector.

SupplierEnd

ConnectorEnd

Read only. A pointer to the ConnectorEnd object representing the target end of the relationship.

SupplierID

Long

Read/Write. ElementID of the element at the target end of this connector.

TaggedValues

Collection

Read only. Collection of ConnectorTag objects.

TransitionAction

String

Read/Write. See the Transition topic for appropriate values.

TransitionEvent

String

Read/Write. See the Transition topic for appropriate values.

TransitionGuard

String

Read/Write. See the Transition topic for appropriate values.

Type

String

Read/Write. Connector type. Valid types are held in the t_connectortypes table in the .EAP file.

VirtualInheritance

String

Read/Write. For Generalization, indicates if inheritance is virtual.

Width

Long

Read/Write. Specifies the width of the connector.

Connector Methods

Method

Type

Notes

GetLastError ()

String

Returns a string value describing the most recent error that occurred in relation to this object.

This function is rarely used as an exception is thrown when an error occurs.

MiscData (long Index)

String

Read only. This low-level property provides information about the contents of the PDatax 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) to PData2

Parameters:

  • Index: long - the zero based index of the PData field to access.

Update ()

Boolean

Update the current ConnectorObject after modification or appending a new item. If false is returned, check the GetLastError function for more information.
