[Geotools-devel] Filter intergration effort

[Jody G. <jga...@re...>]

So far I have turned up a few more over sights in the geoapi filter 
interfaces. Right now visitors only opperates on the closed set of 
defined interfaces (not to mention a few of the visit methods are in the 
wrong class).

I tried writing a blog post on the tradeoffs of visitor use for 
traversal for the benifit of those arriving at geotools/geoapi with an 
XML background.

Along the way I have a good idea for acomplishing transformation in an 
object oriented manner. You may have seen a bunch of scary one-off code 
where Query is transformed between CRSs. I did a quick example with 
applying a Expression transformation to a Filter, but the idea should be 
sound.
