Could someone post an example or a link that shows how to use the "contains"
operator... HEre's the scenario:
I've got the following class that has partnerList collection of Partner
objects - the partnerList is a HashMap keyed by partnerID:
public class GateOut {
private String portID;
private Map partnerList; <-- Collection...
..
}
public class Partner {
private String partnerId;
private String partnerName;
private int purpose;
..
}
Need to write a rule that will determine if a specific PartnerID exists in
the partnerList HashMap. Could you please point me to an example? The
documentation example listed is unclear to me...
thanks -
james

Still having trouble with the contains operator... I have the following rule
in place:
rule "Shipper List Match"
when
$shipperGO : GateOut ( customerId == "Walmart", partnerList contains
("2900") )
then
myService.sendNotification($shipperGO, Constants.SHIPPER_MATCH);
end
--------------------------------------------------------------------------------------------------
and the folllowing code that builds the partnerList collection object:
GateOut walmartGO = new GateOut();
walmartGO.setCustomerId("Walmart");
walmartGO.setContainerId("2939392");
walmartGO.setMatched(false);
walmartGO.setSourceLocation("SHGH");
walmartGO.setDestLocation("SFCO");
Partner shipper = new Partner();
shipper.setPartnerId("2900");
shipper.setPartnerName("Yellow Freight");
shipper.setPurpose(Partner.FORWARDER);
HashMap hm = new HashMap();
hm.put(shipper.getPartnerId(), shipper);
walmartGO.setPartnerList(hm);
-----------------------------------------------------------------------
At runtime, I get the ClassCastException:
at
com.maersk.nam.gems.gatein.walmart.GateOutWalmartExample.main(GateOutWalmartExample.java:62)
Caused by: java.lang.ClassCastException: java.util.HashMap
Can someone help with the proper expression?

contains works on the Collection interface. So if parnerList is a ArrayList
of String, then you could do:
parnerList contains "2900"

Ok thanks - that worked when partnerList was an ArrayList, how would I code
my "contains" condition if the parternList was a HashMap!?

You could write an accessor in your model called getPartnerListKeys()
which returns getPartnerList().keySet() and then use (partnerListKeys
contains "2900") in your rule.
I'm not 100% sure (started with JBoss Rules only a couple of days
ago), but I'm pretty confident that this should work.

That worked just fine - thanks very much for clarification - I'm starting to
understand how that works now... example is worth a thousand lines of
documentation text... :)
