BloombergLP::bslstl::Variant_IsMoveConstructibleAll

This component-private metafunction is derived from bsl::true_type if all template parameters are move constructible, and bsl::false_type otherwise.

Synopsis

Declared in <bslstl_variant.h>

template<
    class t_HEAD,
    class... t_TAIL>
struct Variant_IsMoveConstructibleAll
    : bsl::integral_constant<bool, std::is_move_constructible<t_HEAD>::value && Variant_IsMoveConstructibleAll<t_TAIL...>::value>

Base Classes

NameDescription
bsl::integral_constant<bool, std::is_move_constructible<t_HEAD>::value && Variant_IsMoveConstructibleAll<t_TAIL...>::value>Metafunction representing a compile-time constant of the specified (template parameter) t_TYPE with the specified (template parameter) t_VALUE.

Type Aliases

NameDescription
type Alias for this integral_constant specialization.
value_type Alias for the (template parameter) t_TYPE.

Member Functions

NameDescription
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

NameDescription
value The compile-time constant value of this metafunction.

Specializations

NameDescription
Variant_IsMoveConstructibleAll<t_HEAD> This partial specialization of Variant_IsMoveConstructibleAll is the base case of the recursion, reached when a single template parameter, t_HEAD, remains.
