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

Connector Attributes

Attribute	Remarks	See also
Alias	String Notes: Read/Write An optional alias for this connector.
AssociationClass	Element Notes: Read Only Returns the Association Class element if the connector has one; otherwise NULL/.	Element Class
ClientEnd	ConnectorEnd Notes: Read Only A pointer to the ConnectorEnd object representing the source end of the relationship.	ConnectorEnd Class
ClientID	Long Notes: Read/Write The ElementID of the element at the source end of this connector.
Color	Long Notes: Read/Write Sets the color of the connector.
ConnectorGUID	String Notes: Read Only A system generated, globally unique ID for the current connector.
ConnectorID	Long Notes: Read Only A system generated local identifier for the current connector.
Constraints	Collection Notes: Read Only A collection of constraint objects.	Constraint Class Collection Class
ConveyedItems	Collection of type Element Notes: Read Only Returns a collection of elements that have been conveyed. To add another element to the conveyed Collection, use 'AddNew (ElementGUID,NULL)', where 'ElementGUID' is the GUID of the element to be added.	Element Class Collection Class
CustomProperties	Collection Notes: Read Only Returns a collection of advanced properties associated with an element in the form of CustomProperty objects.	Collection Class CustomProperties Collection
DiagramID	Long Notes: Read/Write The DiagramID of the connector.
Direction	String Notes: Read/Write 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
EndPointX	Long Notes: Read/Write 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.
EndPointY	Long Notes: Read/Write The y-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.
EventFlags	String Notes: Read/Write A structure to hold a variety of flags concerned with event signaling on messages.
FQStereotype	String Notes: Read Only The fully-qualified stereotype name in the format "Profile::Stereotype". One or more fully-qualified stereotype names can be assigned to StereotypeEx.
ForeignKeyInformation	String Notes: Read Only Returns the Foreign Key information.
IsLeaf	Boolean Notes: Read/Write A flag indicating that the connector is a leaf.
IsRoot	Boolean Notes: Read/Write A flag indicating that the connector is a root.
IsSpec	Boolean Notes: Read/Write A flag indicating that the connector is a specification.
MessageArguments	String Notes: Read Only The connector Message arguments.
MetaType	String Notes: Read Only The connector's domain-specific meta type, as defined by an applied stereotype from an MDG Technology.
MiscData	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
Name	String Notes: Read/Write The connector name.
Notes	String Notes: Read/Write Descriptive notes about the connector.
ObjectType	ObjectType Notes: Read Only Distinguishes objects referenced through a Dispatch interface.	ObjectType
Properties	Properties Notes: Returns a list of specialized properties applicable 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.	Properties Class
ReturnValueAlias	String Notes: Shows the 'Return Value Alias' field of the operation.
RouteStyle	Long Notes: Read/Write The route style.
SequenceNo	Long Notes: Read/Write The SequenceNo of the connector.
StartPointX	Long Notes: Read/Write The x-coordinate of the connector's start point. Connector end points are specified in Cartesian coordinates with the origin to the top left of the screen.
StartPointY	Long Notes: Read/Write The y-coordinate of the connector's start point. Connector end points are specified in Cartesian coordinates with the origin to the top left of the screen.
StateFlags	String Notes: Read/Write A structure to hold a variety of flags concerned with State signaling on messages; the list is delimited by semi-colons.
Stereotype	String Notes: Read/Write Sets or gets the stereotype for this connector end.
StereotypeEx	String Notes: Read/Write All the applied stereotypes of the connector in a comma-separated list. Reading the value will provide the stereotype name only; assigning the value accepts either fully-qualified or simple names.
StyleEx	String Notes: Read/Write Advanced style settings; reserved for the use of Sparx Systems.
Subtype	String Notes: Read/Write A possible subtype to refine the meaning of the connector.
SupplierEnd	ConnectorEnd Notes: Read Only A pointer to the ConnectorEnd object representing the target end of the relationship.	ConnectorEnd Class
SupplierID	Long Notes: Read/Write The ElementID of the element at the target end of this connector.
TaggedValues	Collection of type ConnectorTag Notes: Read Only The collection of ConnectorTag objects.	Collection Class ConnectorTag Class
TemplateBindings	Collection of type TemplateBinding Notes: Read Only A collection of TemplateBinding objects.	Collection Class TemplateBinding Class
TransitionAction	String Notes: Read/Write See the Transition topic for appropriate values.	Transition
TransitionEvent	String Notes: Read/Write See the Transition topic for appropriate values.
TransitionGuard	String Notes: Read/Write See the Transition topic for appropriate values.
Type	String Notes: Read/Write The connector type; valid types are held in the t_connectortypes table in the .eap file.
VirtualInheritance	String Notes: Read/Write For Generalization, indicates if the inheritance is virtual.
Width	Long Notes: Read/Write Specifies the width of the connector.

Connector Methods

Method	Remarks	See also
GetLastError()	String Notes: Returns a string value describing the most recent error that occurred in relation to this object.
IsConnectorValid()	Boolean Notes: Queries Enterprise Architect's internal relationship validation schema on the current connector. If False is returned, check the 'GetLastError()' function for more information.
Update()	Boolean Notes: Updates the current ConnectorObject after modification or appending a new item. If False is returned, check the 'GetLastError()' function for more information.
