operator()() [2/2]

template<typename F>

void lsst::afw::table::detail::SchemaMapperImpl::VisitorWrapper< F >::operator() ( KeyPairVariant const &  v ) const

inline

Invoke the visitation.

The call to boost::apply_visitor will call the appropriate template of operator().

This overload allows a VisitorWrapper to be applied directly on a variant object with function-call syntax, allowing us to use it on our vector of variants with std::for_each and other STL algorithms.

Definition at line 70 of file SchemaMapperImpl.h.

{ boost::apply_visitor(*this, v); }
