boost::static_visitor — Convenient base type for static visitors.
template<typename ResultType> class static_visitor { public: // types typedef ResultType result_type; // Exposes result_type member as required by StaticVisitor concept. };
Denotes the intent of the deriving class as meeting the requirements of a static visitor of some type. Also exposes the inner type result_type as required by the StaticVisitor concept.
Notes: static_visitor is intended for use as a base type only and is therefore non-instantiable.
