i'm new to easy rules. its simplicity is very appealing.
i have a candidate problem to solve: our boat club allocates docks based on member seniority. applications (bids) are submitted when a dock becomes available. when bids are submitted they will have a seniority number as an attribute. so the problem is to find the bid with the lowest seniority number.
so in psuedo code the rule might be:
rule seniorityRule
when fact/bid has seniority number < currentLowNumber
then replace currentLowNumber with currentBidNumber
easy-rules appears to be well suited to rules which involve a condition referencing a constant
not rules which compare a fact to a fact.
so here are my questions:
1) where should i hold the currentLowNumber (as a fact or somewhere else? if it's a fact when/where do i retrieve it to compare? thru a listener before the rule executes?)
2) how is the search terminated? thru another rule like:
rule bidWinner
when there doesn't exist a bid with a lower seniority <== not sure how to code or
it's even possible
then display "and the winner is member with " currentLowNumber
