Re: [Doxygen-users] Doxygen not showing friend operators of C++ base class

[Maarten de J. <mj...@ni...>]

Dear Richard,

It actually corresponds to the so-called Barton–Nackman trick which is 
conform the C++ standard.
It is characterized by an in-class friend function definition appearing 
in the base class template
component of the curiously recurring template pattern (CRTP).
This implies that the friend specifier is essential.
