Detailed Description

template<typename EnumType>
class ReverseEnumIterator< EnumType >

bidirectional reverse iterator over an enum type

It can be instantiated using any enum (or C++11 strongly-typed enum) value; the most common expected use scenario has iterators emitted by EnumRange and WholeEnum via standard rbegin() and rend() calls.

In order for the iterator to work, it is mandatory that the underlying enum type's representation values be sequential.

The iterator does not check for bounds; behavior is undefined if the iterator is incremented (or decremented) outside the range representing valid enum symbols (remember: an enum is not a data structure).
