boost::openmethod::virtual_traits

Traits for types used as virtual parameters.

Synopsis

template<
    typename T,
    class Registry>
struct virtual_traits;

virtual_traits must be specialized for each type that can be used as a virtual parameters. It enables methods to:

find the type of the object the argument refers to (e.g. `Node` from `Node&`)
obtain a non‐modifiable reference to that object (e.g. a `const Node&` from `Node&`)
cast the argument to another type (e.g. cast a `Node&` to a `Plus&`)

Specializations of virtual_traits must provide the members described to the VirtualTraits blueprint.
