Rete has listDefrules and Defrule has getConditionalElements, which lets you retrieve its constituents, depending on it being a Pattern or Accumulate; if it is a Group you must recurse down... It's like walking an AST
RHS is similar. But note that fact modifications are possible in functions, so if one of these is called on the RHS, you'll have to investigate in depth. Expect to have some fun ;-) Cheers Wolfgang On 14/08/2013, Przemyslaw Woznowski <p.r.woznow...@cs.cf.ac.uk> wrote: > Dear Jess users. > > What I am trying to do is to dynamically list all the defrules together > with their LHS and RHS facts excluding any conditions.
