This struct template implements the is_member_pointer meta‐function defined in the C++11 standard [meta.unary.comp]to determine if the (template parameter) t_TYPE is a member pointer type. This struct derives from bsl::true_type if the t_TYPE is a member pointer type, and from bsl::false_type otherwise. Additional specializations are provided below to give the correct answer in all cases.

Specializations

Name

Description

is_member_pointer<t_TARGET_TYPEt_HOST_TYPE::*>

This partial specialization provides the true_type result for a (cv‐unqualified) pointer‐to‐member type. Note that additional partial specializations are required to handle the cv‐qualified cases.

is_member_pointer<t_TARGET_TYPE volatilet_HOST_TYPE::*>

This partial specialization provides the true_type result for a volatile‐qualified pointer‐to‐member type.

is_member_pointer<t_TARGET_TYPE constt_HOST_TYPE::*>

This partial specialization provides the true_type result for a const‐qualified pointer‐to‐member type.

is_member_pointer<t_TARGET_TYPE const volatilet_HOST_TYPE::*>

This partial specialization provides the true_type result for a const volatile‐qualified pointer‐to‐member type.
