Visitable< TOOL > Class Template Reference

#include "lib/visitor.hpp"

Description

template<class TOOL = Tool<>>
class lib::visitor::Visitable< TOOL >

Marker interface or base class for all "Visitables".

Concrete types to be treated by a "visiting tool" derive from this interface and need to implement an #apply(Tool&), forwarding to the (internal, static, templated) dispatchOp. This is done best by using the DEFINE_PROCESSABLE_BY macro.
