Hi all, Okay, ANTLR has quite a steep learning curve. It took me some hours to create the first useful code. But then it's just great.
It does exactly what I want: Parse the request and create an object tree representing it. It is possible to influence the structure of the tree and even the classes of the tree nodes. One solution would be extending the ANTLR tree nodes (AST) and implement an implementation independent, request representing interfaces. AFAIK it is also possible to take full control of the tree generation. Probably the best thing is that it is possible to manually transform the RFC ABNF. This could be done by achieving a nearly 1:1 relation between the entities from the ABNF and ANTLR rules. This allows a straight forward development and makes review for correctness quite effective. A positive side effect: Abstraction often costs some extra time lost in the frameworks. In this case the generated code seems to be optimized for speed. Conclusion: IMO the best way to handle complex parsing. Maybe even for simple parsing. :-) Joachim --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
