Classes implementing OuterIterator can be used to iterate over iterators.

OuterIterator extends Iterator {

/* Methods */

public Iterator getInnerIterator ( void )

/* Inherited methods */

abstract public mixed Iterator::current ( void )

abstract public scalar Iterator::key ( void )

abstract public void Iterator::next ( void )

abstract public void Iterator::rewind ( void )

abstract public boolean Iterator::valid ( void )

}
