Re: [rules-users] Find the lowest and highest dates
I'm beginning to think that there is no min or max accumulates in 5.0. If
that's the case, then the accumulate function gets way too complicated (I
can see why I was asked not to use accumulate!)
In that case, is using java in the Then segment the way I've shown the best
technique?
Here's the accumulate I was asked to simplify, that does work:
$lh : BeginAndEndDates() from accumulate(
ServiceLineDetail(
serviceRelatedDates != null,
serviceRelatedDates.serviceDates != null,
$beginDate : serviceRelatedDates.serviceDates.beginDate,
$endDate : serviceRelatedDates.serviceDates.endDate
)
from $claim.serviceLineInfoList,
init(BeginAndEndDates lh = new BeginAndEndDates(); boolean first = true;),
action(
if (first && $beginDate != null) {lh.setBeginDate($beginDate); first =
false; };
if ($beginDate != null && $beginDate.isBefore(lh.getBeginDate()))
lh.setBeginDate($beginDate);
if ($endDate != null && $endDate.isAfter(lh.getEndDate()))
{lh.setEndDate($endDate); };
),
result(lh)
);
