Detailed Description

template<typename Expr>
struct boost::proto::result_of::value< Expr >

A metafunction that returns the type of the value of a terminal Proto expression.

Member Typedef Documentation

template<typename Expr>

typedef detail::term_traits<typename Expr::proto_child0>::value_type boost::proto::result_of::value< Expr >::type

The "value" type of the child, suitable for storage by value, computed as follows:

• T const(&)[N] becomes T[N]
• T[N] becomes T[N]
• T(&)[N] becomes T[N]
• R(&)(A0,...) becomes R(&)(A0,...)
• T const & becomes T
• T & becomes T
• T becomes T

template<typename Expr>

typedef Expr::proto_child0 boost::proto::result_of::value< Expr >::value_type

The raw type of the Nth child as it is stored within Expr.

This may be a value or a reference
