std::iterator_traits< _Iterator > - Traits class for iterators.
SYNOPSIS
Detailed Description
template<typename _Iterator>
struct std::iterator_traits< _Iterator >"Traits class for iterators.
This class does nothing but define nested typedefs. The general version simply forwards the nested
typedefs from the Iterator argument. Specialized versions for pointers and pointers-to-const provide
tighter, more correct semantics.
