Base interface for iterators.
iterator provides the standard operators one expects from iterators (==
, !=
, ++
, *
, ->
).
To subclass iterator, you must provide the following methods:
equal
(const exact_type&
) : Equality check.
increment()
: Increment the iterator.
get()
and get_ptr()
: Indirection (as a reference and as a pointer).
