Collaboration diagram for Internal - ccmqmsgque::MqFactoryC* Add:

The constructor have to be a C++ [class] with superclass [MqContextC] …

1. The factory is implemented as a template with ccmqmsgque::MqFactoryCT<class>.
2. The class have to be a sub-class of ccmqmsgque::MqContextC.
3. The class have to provide a factory-constructor like Filter6::Filter6.
4. The factory-constructor is required in the ccmqmsgque::MqFactoryCT::ObjectSelfCreate new function.

example: use class MyServer with public name "MyServer" as a factory-class

#include "LibMqMsgque_cc.hh"
 
using namespace ccmkkernel;
using namespace ccmqmsgque;
 
// package-item
class MyServer : public MqContextC, public MqServerSetupIF {
  friend class MqFactoryCT<MyServer>;
  private:
    // define the factory constructor
    MyServer(MK_TYP const typ, MqContextC* tmpl=NULL) : MqContextC(typ,tmpl) {};
 
  private:
    // service to serve all incoming requests for token "HLWO"
    void MyFirstService () {
      SendSTART();
      SendV("%s World", ReadSTR());
      SendRETURN();
    }
 
    // define a service as link between the token "HLWO" and the callback "MyFirstService"
    void ServerSetup() {
      ServiceCreate("HLWO", MqServiceICB(&MyServer::MyFirstService));
    }
};
 
// package-main
int MK_CDECL main(int argc, MK_STRN argv[]) {
  MqMsgque::CcMqSetup();
 
  // setup commandline arguments for later use
  MkBufferListC largs = {argc, argv};
  // create "MyServer" factory… and make it to the default.
  MqFactoryCT<MyServer>::Add("MyServer")->Default();
 
  // inspect commandline-argument for the "factory" to choose… and create a object
  auto srv = MqFactoryCT<MqContextC>::GetCalled(largs)->New();
  // start listen for incoming call's
  try {
    srv->LinkCreate(largs);
    srv->ProcessEvent (MQ_WAIT_FOREVER);
  } catch (const std::exception& e) {
    srv->ErrorCatch(e);
  }
  return srv->Exit();
}
