[rules-users] RE: RE: Struggling with Rule syntax - please help...
Good to hear - YES, I want to use Edson's first example where he uses
List.contains() - his example, however, used just ONE list object and I need
to declare and refer to MULTIPLE list objects asserted into working memory.
COuld you show syntax for multiple list object definitions?
THanks in advance,

Edson's example you refer to used a List.contains() within a "return
value operator" (example 3.13 in the 3.0.5 docs):-
[Edson's example]
rule "retrieving the list"
when
Customer( $custCode : customer_code )
then
List codes = lookupDAO.getLookup( $custCode );
assert( codes );
end
rule "doing something"
when
Customer( $custCode : customer_code )
<-- Bound column
$list : List()
<-- Bound column (to a List() fact which must implement List)
SHIPMENT_MOVE(
customer_code == $custCode,
<-- Field constraint
$sc : ship_code,
<-- Bound column
$dc : deliver_code,
<-- Bound column
$pc : port_code,
<-- Bound column
( $list.containts($sc) || $list.containts($dc) ||
$list.containts($pc) ) <-- Return value operator
)
then
// do something
End
