class | iox::popo::ServerPortUser The ServerPortUser provides the API for accessing a server port from the user side. The server port is divided in the three parts ServerPortData, ServerPortRouDi and ServerPortUser. The ServerPortUser uses the functionality of a ChunkSender and ChunReceiver for receiving requests and sending responses. Additionally it provides the offer / stopOffer API which controls whether the server is discoverable for client ports. |
