BloombergLP::bslmf::MetaInt

Synopsis

Declared in <bslmf_metaint.h>

template<int t_INT_VALUE>
struct MetaInt
    : bsl::integral_constant<int, t_INT_VALUE>

Description

Instantiating this template produces a distinct type for each non-negative integer value. This template has been deprecated in favor of the standard integral_constant template.

Base Classes

Name	Description
`bsl::integral_constant<int, t_INT_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
`Tag`	Tag type encoding `t_INT_VALUE` for overload resolution.
`Type`	This specialization of `MetaInt`.
`type`	Alias for this `integral_constant` specialization.
`value_type`	Alias for the (template parameter) `t_TYPE`.

Enums

Name	Description
`Unnamed enum`	Compile-time integer constants for this metafunction.

Member Functions

Name	Description
`MetaInt` [constructor]	Constructors
`operator()`	Return a copy of the template argument `t_VALUE`.
`operator t_TYPE`	Return a copy of the template argument `t_VALUE`.

Static Member Functions

Name	Description
`tag`	Return a reference to a tag encoding this type's integral value.

Static Data Members

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

Specializations

Name	Description
`MetaInt<0>`	This specialization of `MetaInt` has a `VAL` of zero and is convertible to and from `bsl::false_type`.
`MetaInt<1>`	This specialization of `MetaInt` has a `VAL` of one and is convertible to and from `bsl::true_type`.
