### Where are the java files of NodeConnectorRef?

Hello,

I'm working with the bundle of l2switch-release-beryllium-sr3 and I would like to know the methods of some classes like NodeConnectorRef or Node but I don't find these classes. Someone could tell me where to find them?

import org.opendaylight.yang.gen.v1.urn.opendaylight.inventory.rev130819.NodeConnectorRef;
import org.opendaylight.yang.gen.v1.urn.opendaylight.inventory.rev130819.nodes.Node;


This is the GitHub of l2switch-beryllium: https://github.com/opendaylight/l2switch/tree/stable/beryllium

Thank you.
