Examples of javax.jmdns.JmDNS.list()

javax.jmdns.JmDNS.list()
Returns a list of service infos of the specified type. @param type Service type name, such as _http._tcp.local.. @return An array of service instance.

            assertEquals("We did not get the right type for the resolved service:", service.getType(), info.getType());


            // This will force the resolution of the service which in turn will get the listener called with a service resolved event.
            // The info associated with a service resolved event has all the information available.
            // Which in turn populates the ServiceInfo opbjects returned by JmDNS.list.
            ServiceInfo[] services = registry.list(info.getType());
            assertEquals("We did not get the expected number of services: ", 1, services.length);
            assertEquals("The service returned was not the one expected", service, services[0]);


            assertTrue("We did not get the service resolved event.", capServiceResolvedEvent.hasCaptured());
