This should be the source of immutability of filters. See <CODE>FeatureTypeFactory</CODE>, as that provides a good example of what this should look like. The mutable factory to create immutable objects is a good model for this. The creation methods should only create fully formed filters. This in turn means that all the set functions in the filters should be eliminated. When rewriting this class/package, keep in mind FilterSAXParser in the filter module, as the factory should fit cleanly with that, and should handle sax parsing without too much memory overhead., REVISIT: resolve errors, should all throw errors?</DD></DL><HR><P><!-- ======== NESTED CLASS SUMMARY ======== --><!-- =========== FIELD SUMMARY =========== --><!-- ======== CONSTRUCTOR SUMMARY
