CreateLink Method

The GoToolLinking class calls this method to create a new link between ports.

Syntax

Visual Basic
C#

'Declaration
 
Public Overridable Function CreateLink( _
   ByVal fromPort As IGoPort, _
   ByVal toPort As IGoPort _
) As IGoLink

public virtual IGoLink CreateLink( 
   IGoPort fromPort,
   IGoPort toPort
)

Parameters

fromPort: if null, this method will return null
toPort: if null, this method will return null

Remarks

By default this method creates a copy of the NewLinkPrototype object, assigns the IGoLink.FromPort and IGoLink.ToPort properties. How it adds the new link to this view's document depends on the ports. If both of the ports belong to GoSubGraphBases, it adds the new link to the common parent GoSubGraphBase for both ports. Otherwise it adds the new link to the document's GoDocument.LinksLayer. If the new link is IGoRoutable, its IGoRoutable.UpdateRoute method is called. The LinkCreated event is not raised here; it is raised by DoNewLink.
