These programs implement a publish-subscribe example + * using the "amq.topic" exchange. In the example multiple listeners + * can subscribe to the same queues for TTL messages. + * The TTL messages are all ticker price data. Messages are + * browsed and therefore shared among the multiple listeners. + * Messages timeout using TTL so that they don't stay in the queue + * for too long and fill it up. + * Local exclusive LVQ are also declared for market data. + * + * declare_queues.cpp + * + * Declares several non-exclusive queues bound to the amq:topic exchange + * + * topic_publisher.cpp + * + * Sends messages to the "amq.topic" exchange, using the + * multipart routing keys for ticker price and market data + * Ticker messages are sent using a TTL value. + * + * topic_listener.cpp (this program) + * + * Subscribes to non-exclusive queues in NOT_ACQUIRE mode for + * ticker price data and declares two LVQs for market data. + * + * Multiple listeners can be run at the same time. + * + */ + +#include <qpid/client/Connection.h> +#include <qpid/client/Session.h> + + +using namespace qpid::client; +using namespace qpid::framing; + + +int main(int argc, char** argv) { + const char* host = argc>1 ? argv[1] : "127.0.0.1"; + int port = argc>2 ? atoi(argv[2]) : 5672; + Connection connection; + + try { + connection.open(host, port); + Session session = connection.newSession(); + + + //--------- Main body of program -------------------------------------------- + + // Create a queue named "message_queue", and route all messages whose + // routing key is "routing_key" to this newly created queue. + + session.queueDeclare(arg::queue="TICKER.NYSE", arg::exclusive=false); + session.exchangeBind(arg::exchange="amq.topic", arg::queue="TICKER.NYSE", arg::bindingKey="TICKER.NYSE.#"); + std::cout << "Declared queue Ticker NYSE non-exclusive with amq:topic binding TICKER.NYSE.#" << std::endl; + session.queueDeclare(arg::queue="TICKER.NASDAQ", arg::exclusive=false); + session.exchangeBind(arg::exchange="amq.topic", arg::queue="TICKER.NASDAQ", arg::bindingKey="TICKER.NASDAQ.#"); + std::cout << "Declared queue Ticker NASDAQ non-exclusive with amq:topic binding TICKER.NASDAQ.#" << std::endl; + + + //----------------------------------------------------------------------------- + + connection.close(); + return 0; + } catch(const std::exception& error) { + std::cout << error.what() << std::endl; + } + return 1; + +} + + + |
