boost::proto::functional::make_expr — A PolymorphicFunctionObject equivalent to the
proto::make_expr()
function.
// In header: <boost/proto/make_expr.hpp> template<typename Tag, typename Domain = proto::deduce_domain> struct make_expr : proto::callable { // member classes/structs/unions template<typename This, typename... A> struct result<This(A...)> : proto::result_of::make_expr< Tag, Domain, A... > { }; // public member functions template<typename... A> typename proto::result_of::make_expr< Tag, Domain, A const... >::type const operator()(A const &...) const; };
In all cases, proto::functional::make_expr<Tag, Domain>()(a...)
is equivalent to proto::make_expr<Tag, Domain>(a...)
.
proto::functional::make_expr<Tag>()(a...)
is equivalent to
proto::make_expr<Tag>(a...)
.
make_expr
public member functionstemplate<typename... A> typename proto::result_of::make_expr< Tag, Domain, A const... >::type const operator()(A const &... a) const;
Construct an expression node with tag type Tag
and in the
domain Domain
.
