Metafunction adding top‐level const and volatile qualifiers to a type.
Synopsis
Declared in <bslmf_addcv.h>
template<class t_TYPE>
struct add_cv;Description
This struct template implements the add_cv meta‐function defined in the C++11 standard [meta.trans.cv], providing an alias, type, that returns the result. If the (template parameter) t_TYPE is not a reference type, nor a function type, nor already const‐qualified and volatile‐qualified at the top‐level, then type is an alias to t_TYPE with a top‐level const‐qualifier and a volatile‐qualifier added; otherwise, type is an alias to t_TYPE.
