bsl::is_member_object_pointer

Meta-function for detecting member object pointer types.

Synopsis

Declared in <bslmf_ismemberobjectpointer.h>

template<class t_TYPE>
struct is_member_object_pointer
    : false_type

Description

This struct template implements the is_member_object_pointer meta-function defined in the C++11 standard [meta.unary.cat]to determine if the (template parameter) t_TYPE is a pointer to non-static data member type. This struct derives from bsl::true_type if the t_TYPE is a pointer to non-static data member type, and from bsl::false_type otherwise.
