BOOST_PROTO_EXTENDS_FUNCTION — For adding to an expression extension class a set of overloaded function call operators that build expression templates.
// In header: <boost/proto/extends.hpp>
BOOST_PROTO_EXTENDS_FUNCTION()
Use BOOST_PROTO_EXTENDS_FUNCTION()
after
BOOST_PROTO_BASIC_EXTENDS()
to give an expression
extension class a set of overloaded function call operators that build expression templates.
In addition, BOOST_PROTO_EXTENDS_FUNCTION()
adds a nested
result<>
class template that is a metafunction for
calculating the return type of the overloaded function call operators.
