Detailed Description

template<typename D, typename S>
struct utils::const_clone< D, S >

Helper struct to clone the constness of one type to another.

Warning

It seems *this in a const member function is not a const object, use this, which is a pointer to a const object.

Template Parameters

D	The destination type, it should have no cv-qualifier and not be a pointer or reference.
S	The source type, this type may be a pointer or reference and obviously is allowed to have a cv-qualifier, although volatile has no effect.

pointer

template<typename D , typename S >

using utils::const_clone< D, S >::pointer = std::conditional_t<is_source_const, const D*, D*>
