        public CriterionIterator​(java.util.Iterator<? extends T> iterator,
                         Criterion<? super T> criterion)
        Creates a new CriterionIterator, that filters the objects of the specified iterator using the specified Criterion.

        The specified iterator must not be null.

        The specified criterion may be null, in which case no filtering is done and the returned iterator iterates through all objects of the specified iterator.

        Parameters:
        iterator - underlying iterator whose iteration should be filtered
        criterion - filter-Criterion
