This is surprising:
(deffunction ppallfunctions ()
(bind ?sb (new StringBuffer))
(bind ?it ((engine) listFunctions))
(while (?it hasNext)
(bind ?f (?it next))
;; The following call isn't possible because the intrinsic functions
;; don't implement jess.Visitable, and the only constructor for
;; jess.PrettyPrinter has an argument of this type.
;; (?sb append (new jess.PrettyPrinter (?f)))
(?sb append "
")
)
(?sb toString)
)
OK, one can filter the "unhospitable" functions, but what's the point
in returning objects that cannot be processed in the usual way?
