Draw2d JS How to get the figure that the port is connected to from the connection properties?

Question

I create in one part of code figures an connection between figures, like this:

    var input = figure.createPort("input");
    var output= figure.createPort("output");

but i also need get information about connection in other part of code. I have seen only getSoucrePort() and getTargetPort() In connection's properties that doesn't connected with figure. Does it any way to get source or target figure (not port) in draw2d?
