is_tag_of_member_at_left Struct Reference
[relation]

Metafunction to test if a user tag is refering to the left member. More...

#include <is_tag_of_member_at.hpp>

Detailed Description

Metafunction to test if a user tag is refering to the left member.

template< class Tag, class Relation >
struct is_tag_of_member_at_left : {true_|false_} {};

This metafunction is somewhat redundant with member_with_tag, but it is included because it is a lot easier to metaprogram with it. The result type is the same that:

 is_same< member_with_tag<Tag,Relation>::type , member_at::left >::type

See also member_with_tag, member_at, is_tag_of_member_at_right.
