[pygccxml-development] virtual functions without wrappers

[Neal B. <ndb...@gm...>]

I am playing with pyplusplus, trying out pypp_api.  I noticed that a class 
with virtual functions and inheritance used wrappers, as shown in the 
boost::python tutorial.

I would like to have to option to bypass these wrappers.  IIUC, wrappers are 
only needed if the function will be overidden in python and then called from 
c++.  My intention is a class hierarchy implemented in c++ only that is 
called from python.

Here is a typical example:

struct base { virtual void F() = 0; };

struct impl_1 : base { virtual void F() { do something; } };

struct X {
	X (boost::shared_ptr<base> _p) : p (_p) {}
	boost::shared_ptr<base> p;
	void use_F () { (*p)->F(); }
};

In python then:

i = impl_1()
x = X (i)
x.use_F()
