— the full code sample for publishing

The previous code samples presented the basics of publishing. A publication application initializes channels, proxies, subjects, and attributes for content distribution.

The basic sequence of the publication process in the completed application is:

1. Create a proxy connection for the channel. ( Proxy Initialization)
2. Create a notification for the subject; set the value of the predefined attribute. ( Notification)
3. Publish the notification for the subject over the channel. ( Content publication)

#include "PC_evn_Filter.hpp"

#include "PC_evn_Proxy.hpp"

#include <iostream>

using namespace precache::event;

using std::cerr;

using std::endl;

int

main(int argc, char* argv[])

{

      try

      {

//Create a proxy for the channel and client.

            Proxy p(7,3001);

//Create a notification for the subject.

            Notification n(p,"Sample.Intro1");

//Set the value of the predefined filter.

            n.SetPredefinedAttr("Message","Hello World");

//Publish the notification for the subject.

            p.Publish(n);

      } catch (PCException &e)

      {

            cerr<<e.Message().String()<<endl;

      }

}

In the next chapter, Basic Case, Subscription — C++, we will construct a simple application for retrieving the published message.
