How can I get the selcted connector?

[theonegis]

I noticed that in the SelectionManager interface there are getSelectedNodes(), getSelectedConnections() and getSelectedJoints(). Why there are no getSelectedConnectors()? How can I get the selected connectors in my code? Can anyone help me?

I learnt from the demo example that I can clear all the connectors of a selected node, but still I want to know how to clear a specific selected connector?

I think this the essence of this question is that how to select a connector. I find there is no methods provided to select a connector. Who can help out?
