Re: [boost] determining if an object is faster to pass by value or const reference

John Maddock wrote:

There's nothing to stop you from adding a full or partial specialisation of call_traits to your header:

struct my_value_type{ ... };

namespace boost{

template<> struct call_traits<my_value_type> { typedef my_value_type value_type; typedef my_value_type& reference; typedef my_value_type const& const_reference; typedef my_value_type param_type; };

} // namespace

Then once your functions are call_traits aware, it's then easy to tweek behaviour by adding specialisations as required.

Does this help?

Yes this likely solves my problem. I hope the documentation can be updated to mention that specialization for user defined types is supported. Thanks, Michael Marcin
