Detailed Description

template<typename _Iterator>
class IndirectIterator2< _Iterator >

An iterator that performs three dereferences in operator*().

This is a triple-dereferencing iterator. This is useful when you have an array of pointers to pointers to widgets that you would like to treat as an array of widgets.
