bsl::is_pointer

Synopsis

Declared in <bslmf_ispointer.h>

template<class t_TYPE>
struct is_pointer
    : bsl::false_type

Description

This struct template implements the is_pointer meta-function defined in the C++11 standard [meta.unary.cat]to determine if the (template parameter) t_TYPE is a pointer. This struct derives from bsl::true_type if the t_TYPE is a pointer type (but not a pointer-to-non-static-member type), and bsl::false_type otherwise.

Base Classes

Name	Description
`bsl::false_type`	Metafunction representing the boolean constant `false`.

Specializations

Name	Description
`is_pointer<t_TYPE*>`	This partial specialization of `is_pointer` derives from `bsl::true_type` for when the (template parameter) `t_TYPE` is a (cv-unqalified) pointer type.
`is_pointer<t_TYPE volatile*>`	This partial specialization of `is_pointer` derives from `bsl::true_type` for when the (template parameter) `t_TYPE` is a `volatile` qualified pointer type.
`is_pointer<t_TYPE const*>`	This partial specialization of `is_pointer` derives from `bsl::true_type` for when the (template parameter) `t_TYPE` is a `const` qualified pointer type.
`is_pointer<t_TYPE const volatile*>`	This partial specialization of `is_pointer` derives from `bsl::true_type` for when the (template parameter) `t_TYPE` is a 'const volatile' qualified pointer type.
