Detailed Description

template<typename RangeRef>
class util::details::RangeForWrapperBox< RangeRef >

Class offering begin/end iterators of the same type out of a range of iterators of different types.

Template Parameters

RangeRef

type of reference to be stored (constantness embedded)

The class steals (moves) the value if RangeRef is a rvalue reference type, while it just references the original one otherwise.
