Detailed Description

template<typename _Iterator>
class IndirectIterator< _Iterator >

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

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