JDK 1.2 provides a new Map interface which replaces Dictionary. 2. java.util.Dictionary is an abstract base class not an interface. 3. java.util.dictionary is weakly typed: it doesn't enforce the requirement that keys be strings, and it requires values to be cast to strings. I think it would be much better to have an Attributes interface and also a convenience adapter class that provides a Dictionary implementation in terms of that interface. > endElement (String name) No problem with that. > charData (char ch[], int length) I think there should be an offset argument as well. Most of the Java String operations that operate on a subarray take 3 arguments: char array, offset and count. If you don't have the offset argument you will be requiring some implementations to do additional copying which has a significant performance cost. > I am also assuming that we will provide not only a callback interface, > but also an (optional) base class with stub methods that implementors > can override as needed; that means that novice users will not have to > implement all of SAX, even if we do end up with nine or ten methods. I agree we should provide these. JDK 1.1 does this extensively in AWT: it calls the base classes Adapters. I think we should follow this terminology. James xml-dev: A list for W3C XML Developers.
