boost::openmethod::virtual_traits<boost::type_erasure::any<C, T&>, Registry>

Specialize virtual_traits for the mutable any reference, boost::type_erasure::any<Concept, _self&>, passed by value.

Synopsis

Declared in <boost/openmethod/interop/boost_type_erasure.hpp>

template<
    class C,
    typename T,
    class Registry>
struct virtual_traits<boost::type_erasure::any<C, T&>, Registry>;

Description

The any references are cheap, two‐word handles; passing them by value is the idiomatic way to use them as parameters. Dispatch is on the type bound at construction, obtained via boost::type_erasure::typeid_of ‐ not the C++ RTTI dynamic type of the referent. Concept must contain boost::type_erasure::typeid_<>; relaxed implies it.
