Here's an example that Gordon sends around every year or so.
It creates a selector map on a receiver link to filter messages.
This example shows proper escapement to include hyphens in the filter.
#include <qpid/messaging/Address.h>
#include <qpid/messaging/Connection.h>
#include <qpid/messaging/Message.h>
#include <qpid/messaging/Receiver.h>
#include <qpid/messaging/Session.h>
#include <qpid/types/Variant.h>
#include <iostream>
using namespace qpid::messaging;
using qpid::types::Variant;
int main(int argc, char** argv) {
Connection connection;
try
{
std::string url = argc > 1 ? argv[1] : "localhost:5672";
std::string node = argc > 2 ? argv[2] : "queue";
std::string connectionOptions = argc > 3 ? argv[3] :
"{protocol:amqp0-10}";
connection = Connection(url, connectionOptions);
connection.open();
Session session = connection.createSession();
Variant::Map selector;
selector["selector"] = "\"my-property\"='my-value'";
Variant::Map options;
options["link"] = selector;
Address address(node, "", options);
Receiver receiver = session.createReceiver(address);
Message message;
while (receiver.fetch(message)) {
std::cout << "received: " << message.getContentObject() <<
std::endl;
}
session.close();
connection.close();
return 0;
} catch (const std::exception& error) {
std::cout << "Error: " << error.what() << std::endl;
connection.close();
}
return 1;
}
