BloombergLP::bdlat_CustomizedTypeFunctions::IsCustomizedType

Synopsis

Declared in <bdlat_customizedtypefunctions.h>

template<class TYPE>
struct IsCustomizedType
    : bsl::integral_constant<bool, bslalg::HasTrait<TYPE, bdlat_TypeTraitBasicCustomizedType>::value>

Description

This struct should be specialized for third-party types that need to expose "customized type" behavior. See the component-level documentation for further information.

Base Classes

Name	Description
`bsl::integral_constant<bool, bslalg::HasTrait<TYPE, bdlat_TypeTraitBasicCustomizedType>::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
`IsCustomizedType<bdlar::CustomizedTypeConstRef>`	Trait indicating that `bdlar::CustomizedTypeConstRef` is a `bdlat` customized type.
`IsCustomizedType<bdlar::CustomizedTypeRef>`	Trait indicating that `bdlar::CustomizedTypeRef` is a `bdlat` customized type.

Derived Classes

Name	Description
`IsCustomized`	Meta-function indicating whether the specified `t_TYPE` is a customized type.
