The service discovery library is a C++-wrapper around existing libraries to facilitate publishing and discovering services in a distributed system.

Currently it relies on Avahi (http://avahi.org)

Example

A number of examples for usage of this library can be found in the src/examples folder of the source package.

A simple usage example:

 #include <service_discovery/ServiceDiscovery.hpp>

 using namespace std;
 using namespace servicediscovery::avahi;

 ...

 ServiceConfiguration configuration("test_component","_sd_test_component._tcp");
 configuration.setDescription("description", "This is some information published with with component");

 // Publish a single service
 ServiceDiscovery servicePubisher;
 servicePublisher.start(configuration);


 // Listen for services publish under _sd_test_component._tcp
 std::vector<std::string> serviceTypes;
 serviceTypes.push_back("_sd_test_component._tcp");
 ServiceDiscovery serviceListener;
 serviceListener.listenOn(serviceTypes);

 // Allow services to publish
 sleep(5);


 // Check for existing services (under _sd_test_component._tcp)
 std::vector<ServiceDescription> services =  serviceListener.findServices();
 std::cout << " - Found services: " << std::endl;
 std::vector<ServiceDescription>::iterator it = services.begin();
 for(;it != services.end(); ++it)
 {
     std::cout << it->getName() << std::endl;
 }

 serviceListener.stop();
 serviceDiscovery.stop();
