bsl::is_fundamental

Synopsis

Declared in <bslmf_isfundamental.h>

template<class t_TYPE>
struct is_fundamental
    : integral_constant<bool, is_arithmetic<t_TYPE>::value || is_void<t_TYPE>::value>

Description

This struct template implements a meta-function for checking if a type is fundamental as defined in the C++11 standard [basic.fundamental]. Note that this is subtly differemt from bslmf::IsFundamental, which also returns true_type for references to fundamental types.

Base Classes

Name	Description
`integral_constant<bool, is_arithmetic<t_TYPE>::value \|\| is_void<t_TYPE>::value>`	Metafunction representing a compile-time constant of the specified (template parameter) `t_TYPE` with the specified (template parameter) `t_VALUE`.

Type Aliases

Name	Description
`type`	Alias for this `integral_constant` specialization.
`value_type`	Alias for the (template parameter) `t_TYPE`.

Member Functions

Name	Description
`operator()`	Return a copy of the template argument `t_VALUE`.
`operator t_TYPE`	Return a copy of the template argument `t_VALUE`.

Static Data Members

Name	Description
`value`	The compile-time constant value of this metafunction.

Specializations

Name	Description
`is_fundamental<bsl::nullptr_t>`	Explicit specialization to confirm that the type of `nullptr` is fundamental.
`is_fundamental<bsl::nullptr_t volatile>`	Explicit specialization to confirm that the type of `volatile nullptr` is fundamental.
`is_fundamental<bsl::nullptr_t const>`	Explicit specialization to confirm that the type of `const nullptr` is fundamental.
`is_fundamental<bsl::nullptr_t const volatile>`	Explicit specialization to confirm that the type of `const volatile nullptr` is fundamental.
