[cpp] forward callContext of a processor into methods of a handler

[Николай Рапоткин]

Hi all,

I have a common issue: inside handler method check if sender is authorized
and know who he/she is. And I faced with that providing some "additional"
parameters to request handler is very difficult. In spite of there are two
contexts (server and processor) they can't really change a soem_method_args
structure but they can be very useful is case of doing some preprocessing.

So, I suggest to forward callContext into methods of handler as very last
parameter.

A generated code might look like the following:

class SomeServiceIf {
 public:
  virtual ~ SomeServiceIf () {}
  virtual void someMethod() = 0;
  virtual void someMethod(void* context) {
    someMetho();  // For backward compatibility
  }
}

In this case I could access callContext and get out sender Info for instance

Does it even make sense or there is the easier way to do it?

Best regards,

Nikolay.
