Synopsis

Declared in <bslmf_isconvertible.h>

template<
    class t_FROM_TYPE,
    class t_TO_TYPE>
struct is_convertible
    : bsl::integral_constant<bool, ::std::is_convertible<typename BloombergLP::bslmf::IsConvertible_CheckComplete<t_FROM_TYPE>::type, typename BloombergLP::bslmf::IsConvertible_CheckComplete<t_TO_TYPE>::type>::value>

Description

This struct template implements the is_convertible meta-function defined in the C++11 standard to determine whether the (template parameter) t_FROM_TYPE is implicitly convertible to the (template parameter) t_TO_TYPE.

Base Classes

Name	Description
`bsl::integral_constant<bool, ::std::is_convertible<typename BloombergLP::bslmf::IsConvertible_CheckComplete<t_FROM_TYPE>::type, typename BloombergLP::bslmf::IsConvertible_CheckComplete<t_TO_TYPE>::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.
