Trait< TY, YES > Struct Template Reference

#include "lib/polymorphic-value.hpp"

Description

template<class TY, class YES = void>
struct lib::polyvalue::Trait< TY, YES >

trait template to deal with different ways to support copy operations.

Default is no support by the API and implementation types. In this case, the CopySupport interface is mixed-in at the level of the concrete implementation class and will be accessed later on through a dynamic_cast<CopyAPI&>

Todo:

this whole decision logic works but is confusingly written ///////////////////////TICKET #1197 : improve design of copy support
