[javascript-dev] checking status of an objects connections

Hi

I apologize if this is a foolish question...

I am new to js, and I am wondering if there is a way to check if an  object is connected to anything. I know how to connect or disconnect objects, but essentially I am trying to ask if obj a is connected to obj b, if not then connect, if so then disconnect. I couldn't find it in the documentation.

Thanks!
