alib::enumops::EnumIterator< TEnum >::TRandomAccessIterator< TPointer, TReference > Class Template Reference

Description:

template<typename TEnum>
template<typename TPointer, typename TReference>
class alib::enumops::EnumIterator< TEnum >::TRandomAccessIterator< TPointer, TReference >

Implementation of std::iterator_traits for enum type TEnum. This class exposes ConstIterator which uses const TEnum* and const TEnum& as pointer and reference types.

As the name of the class indicates, this iterator satisfies the C++ standard library concept RandomAccessIterator .
