+Filtered iterators restrict the scope of existing iterators even
+more. For instance, you could imagine to iterate over the the subset
+of those @ref GlossActive "active cells" having their user flag set or
+belonging to a certain subdomain.
+
+This is achieved by using an object of type FilteredIterator
+&lt;BaseIterator&gt;, where BaseIterator usually is one of the
+standard iterators discussed above.
+
+The FilteredIterator gets an additional Predicate in its constructor
+and will skip all objects where this Predicate evaluates to
+<tt>false</tt>. A collection of already implemented predicates can be
+found in the namespace IteratorFilters.
