Subject: JESS: Finding Facts by name within a Jess User Defined Function
I want to write a function that needs to find a fact by name. For example I need to find the fact "MAIN::work-surface" and evaluate it's slot values. Is there a way to search through all the facts to find a certain one?
f-0 (MAIN::initial-fact)
f-1 (MAIN::vocabulary (product work-surface))
f-2 (MAIN::work-surface (shape rectangular) (product-line 2) (depth 24) (width 62) (order-string "Z2R,BUL,G4,62,24E,1X,CO,ED") (shape-code R) (top-material L) (top-finish 1X) (top-finish-entered not-defined) (front-edge E) (front-edge-finish ED) (side-edge not-defined) (side-edge-finish CO) (secondary-finish BU) (b ack-edge-cord-drop G4) (support-type not-defined))
For a total of 3 facts.
TIA
