class wpi::iterator_adaptor_base< DerivedT, WrappedIteratorT, IteratorCategoryT, T, DifferenceTypeT, PointerT, ReferenceT >

CRTP base class for adapting an iterator to a different type.

This class can be used through CRTP to adapt one iterator into another. Typically this is done through providing in the derived class a custom operator* implementation. Other methods can be overridden as well.
