Connect a connector

This is a sample of how to create a connector by associating models. When using this sample to connect a connector on a diagram,

• A reference association class must exist between the models of the two nodes you select
• A connector shape that models the above association must already be defined in the diagram.

public void CreateConnectors(ICommandContext c, ICommandParams p) 
{ 
//Get the currently displayed diagram 
IDiagram diagram = c.App.Workspace.CurrentEditor as IDiagram; 
if (diagram == null) 
{ 
//If no diagram is displayed, terminate the process 
c.App.Output.WriteLine("sample", "Diagram not displayed."); 
return; 
} 

//Get the nodes selected on the diagram 
IEnumerable<INode> nodes = diagram.GetSelectedShapes().OfType<INode>(); 
if (nodes.Count() != 2) 
{ 
c.App.Output.WriteLine("sample", "Please select only two nodes."); 
return; 
} 

//Attach all possible reference fields between the selected nodes 
INode node = nodes.ElementAt(0); 
INode other = nodes.ElementAt(1); 
node.Model.RelateAll(other.Model); 
} 

To remove a connector connection, delete the association between the models that correspond to the shape. For more information on adding and deleting associations, see Relating Models.

public void CreateConnectors(ICommandContext c, ICommandParams p) 
{ 
//Get the currently displayed diagram 
IDiagram diagram = c.App.Workspace.CurrentEditor as IDiagram; 
if (diagram == null) 
{ 
//End processing if no diagram is displayed 
c.App.Output.WriteLine("sample", "Diagram not displayed"); 
return; 
} 

//Get the connectors selected on the diagram 
IEnumerable<IConnector> connectors = diagram.GetSelectedShapes().OfType<IConnector>().ToList(); 
if (!connectors.Any()) 
{ 
c.App.Output.WriteLine("sample", "No connector selected"); 
return; 
} 

//Disassociate the connectors in the relationships that correspond to the connectors obtained 
foreach(IConnector connector in connectors) 
{ 
IRelationship relationship = connector.Model as IRelationship; 
c.App.Output.WriteLine("sample", $"UnRelate Relation: {relationship.Metaclass.Name}"); 
c.App.Output.WriteLine("sample", $" Connector SourceField: {relationship.SourceField.Name}"); 
c.App.Output.WriteLine("sample", $" Connector TargetField: {relationship.TargetField.Name}"); 
relationship.UnRelate(); 
} 
}
