[Cppcms-users] Page handlers from configuration

[Saikumar G. <sai...@gm...>]

Before I reinvent the wheel, I wanted to check with you first to see if there 
is an easier method to accomplish this.

Goal: I want to specify the dispatch handler method through means of a class 
whose instance is created through a class factory using a service name.
Why: So that we can specify the page handlers through the configuration file and
 not touch the main module for adding/updating/deleting a page. 

You can notice that the service module is created using a class factory and used 
for the assign method in dispatcher.
I know the below code is wrong and will not work, but wanted to show you the 
concept what I would like to accomplish.
Any ideas ?

void CPPCMSServer::initmapping( cppcms::service &srv ) {
	  string page = "/login"; // Read from the configuration
	  // Creates an instance of LoginServiceModule
	  ServiceModule *sm = CreateServiceModuleFactory(page);  
          dispatcher().assign(page, &ServiceModule::processRequest, sm);
}

class ServiceModule
{
public:
    virtual void processRequest(cppcms::application &app) = 0;
};

class LoginServiceModule : public ServiceModule {
public:
    LoginServiceModule() {}
    void processRequest(cppcms::application &app);
};

void LoginServiceModule::processRequest(cppcms::application &app) {
    // Process page request for "/main/login" page.
}
