<p>
Perform service discovery session:
</p>
<pre>
<samp>
int timeout = 500; // milliseconds
String query = "_services._dns-sd._udp.local."; //DNS-SD query
//instantiate protocol by name attribute
IProtocol protocol = ProtocolFactory.getProtocol("DNS-SD");
//instantiate transport by name attribute
ITransport transport = TransportFactory.getTransport("UDP", "224.0.0.251", timeout);
//get engine instance and kick off discovery
ServiceDiscoveryEngine serviceDiscoveryEngine = ServiceDiscoveryEngine.getInstance();
serviceDiscoveryEngine.doServiceDiscovery(query, protocol,transport);
</samp>
</pre>
<p>
Access EMF model:
</p>
<pre>
<samp>
//get engine instance
ServiceDiscoveryEngine serviceDiscoveryEngine = ServiceDiscoveryEngine.getInstance();
//access org.eclipse.emf.ecore.resource.Resource
Resource model = serviceDiscoveryEngine.getResource();
</samp>
