Interface NetworkTopologyDiscovery

All Known Implementing Classes:
NetworkTopologyDiscoveryImpl
public interface NetworkTopologyDiscovery
This class is used to resolve the list of Internet address to use when attaching JmDNS to the network.

To create you own filtering class for Internet Addresses you will need to implement the class and the factory delegate. These must be called before any other call to JmDNS. 

 public static class MyNetworkTopologyDiscovery implements NetworkTopologyDiscovery {

     @Override
     public InetAddress[] getInetAddresses() {
         // TODO Auto-generated method stub
         return null;
     }

     @Override
     public boolean useInetAddress(NetworkInterface networkInterface, InetAddress interfaceAddress) {
         // TODO Auto-generated method stub
         return false;
     }

 }

 public static class MyClass implements NetworkTopologyDiscovery.Factory.ClassDelegate {
     public MyClass() {
         super();
         NetworkTopologyDiscovery.Factory.setClassDelegate(this);

         // Access JmDNS or JmmDNS
     }

     @Override
     public NetworkTopologyDiscovery newNetworkTopologyDiscovery() {
         return new MyNetworkTopologyDiscovery();
     }

 }
