Re: [rules-users] Matching on instanceof without eval?

Edson, I do not assert the Instruments, on the Positions which contains multiple Instruments. I an trying to match Option Positions (ie, Positions that contain one or more Option legs). What I did was... when position : Position(option : instrument, option.class == OptionInstrument) ...and this works correctly. Is the above more or less efficient than using eval or the from-clause? It certainly is easier to read. thanks! -barry -- View this message in context: http://www.nabble.com/Matching-on-instanceof-without-eval--tp17425953p174...
