24.9. Pet Store Example: Doing the Checkout Extract from PetStore.drl
rule "do checkout" dialect "java" when then doCheckout(frame, drools.getWorkingMemory()); end
- The rule
"do checkout"
has no agenda group set and no auto-focus attribute. As such, it is deemed part of the default (MAIN) agenda group. This group gets focus by default when all the rules in agenda-groups that explicitly had focus set to them have run their course. - There is no LHS to the rule, so the RHS will always call the
doCheckout()
function. - When calling the
doCheckout()
function, the rule passes the globalframe
variable to give the function a handle to the Swing GUI. - The
doCheckout()
function shows a confirmation dialog to the user. If confirmed, the function sets the focus to the checkout agenda-group, allowing the next lot of rules to fire.
