Creating connector [message #559816]

Hi,

I need to create a Connector between two ports, I listened to the notification on the model when I create a Connector by hand and I discovered that the Connector is owned by the Class and not by the Port and that no notification is fired from Port, so I don't know if this code is right:

//port1, port2 are the ports to be connected

Connector conn = UMLFactory.eINSTANCE.createConnector();
port1.getEnds().add(conn.createEnd());
port2.getEnds().add(conn.createEnd());

Is it right?

Thanks in advance, 123star

I would expect you to have to add the connector to some parent in the model.

StructuredClassifier#createOwnedConnector(String) would do that for you:

StructuredClassifier parent = (StructuredClassifier) port1.getNamespace();
Connector conn = parent.createOwnedConnector(null);

Re: linking connector end with the port - what you are doing should work, but in the end, adding to the ends collection will result on setRole(port) on the connection end. IOW:

port1.getEnds().add(conn.createEnd());

is equivalent to:

ConnectorEnd end1 = conn.createEnd();
end1.setRole(port1);

But I haven't tried any of the code above. Cheers,

Rafael
