Member Function Documentation

operator()() [1/2]

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); }

template<typename F >

template<typename T >

void lsst::afw::table::detail::SchemaMapperImpl::VisitorWrapper< F >::operator() ( std::pair< Key< T >, Key< T > > const &  pair ) const
