[rules-users] Maps as Object in Drools

Hi All, I was reading the following thread from august 2009: http://lists.jboss.org/pipermail/rules-users/2009-August/010178.html I would like write a clojure DSL for drools similar to what André was trying to do and I also feel that using maps as fact-objects would be the most idiomatic for Clojure (at least in the general case!). I am interested by the idea of implementing ObjectType and Accessor interfaces proposed by Edson. It seems that this would be a good fit with Drools and that (if understand correctly!) it would allow the map properties to be properly indexed by the rules engine. However I cannot seem to find these interfaces (ObjectType and *Accessor) in the current API. http://docs.jboss.org/drools/release/5.4.0.CR1/knowledge-api-javadoc/inde... Could someone show me where these classes are documented? Or were they moved or replaced? Maybe there is some source code that would make a good example? Thanks for your help, Frank
