** \brief An iterator adapter for the Java bindings, giving Java iterators
** the ability to access elements from STL iterators.
**
** An iterator adapter for the Java bindings, giving Java iterators the
** ability to access elements from STL iterators. This class is mapped
** into Java by SWIG, where it implements Iterator (some additional
** Java-side functions are added by the SWIG layer to implement the full
** interface).
**
** The functionality requires significant assistance from the ".i" SWIG
** interface files, applying a variety of typemaps.
