RE: [rules-users] RE: RE: Struggling with Rule syntax - please help...
Something like this?
rule "Codes1"
when
then
Codes1List codes1 = lookupDAO.getLookup( CODES_1 ); <--
Codes1List is a subclass of List
assert( codes1 );
end
rule "Codes2"
when
then
Codes2List codes2 = lookupDAO.getLookup( CODES_2 ); <--
Codes2List is a subclass of List
assert( codes2 );
End
rule "Codes3"
when
then
Codes3List codes3 = lookupDAO.getLookup( CODES_3 ); <--
Codes3List is a subclass of List
assert( codes3 );
End
rule "doing something"
when
Customer( $custCode : customer_code )
$codes1 : Codes1List()
$codes2 : Codes2List()
$codes3 : Codes3List()
SHIPMENT_MOVE(
customer_code == $custCode,
$sc : ship_code,
$dc : deliver_code,
$pc : port_code,
( $codes1.containts($sc) || $codes2.containts($dc) ||
$codes3.containts($pc) )
)
then
// do something
End
Otherwise you'll need to explain your model to me and what you're trying
to achieve a little more.
Thanks,
Mike

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
