## Class template static_visitor

boost::static_visitor — Convenient base type for static visitors.

## Synopsis

    template<typename ResultType>
    class static_visitor {
    public:
      // types
      typedef ResultType result_type;  // Exposes result_type member as required by StaticVisitor concept.
    };

## Description

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 noninstantiable.
