BloombergLP::bslmf::InvokeResult_MemPtrArgQualifiers<t_MEMOF_CLASS, t_ARG

Propagate cv and reference qualifiers from a dereferenced invoke argument.

Synopsis

Declared in <bslmf_invokeresult.h>

template<
    class t_MEMOF_CLASS,
    class t_ARG_TYPE>
struct InvokeResult_MemPtrArgQualifiers<t_MEMOF_CLASS, t_ARG_TYPE, false>
    : /* implementation-defined */

Description

This metafunction determines which cv qualifiers and reference qualifiers should be propagated from the first argument of invoke_result.

This specialization is instantiated when t_ARG_TYPE is not derived from t_MEMOF_CLASS and is assumed to be a pointer or smart pointer type. If type A is the result of dereferencing an object of type t_ARG_TYPE, then the constant k_IS_LVALUE is true iff A is an lvalue reference; the constant k_IS_CONST is true iff A is a const‐qualified reference; and the constant k_IS_VOLATILE is true iff A is a volatile‐qualified reference.
