Re: [rules-users] Getting Latest Matching Fact
You'll have to separate the logic for determining that the item you
are looking for is in the list from the access to the first occurrence.
rule "find first 'car'"
when
$p1:Policy()
$carList: List( size > 0 )
from collect ( Vehicle( name == "car" )
from $p1.vehicleslist )
$first: Vehicle( ) from $carList.get( 0 )
then
System.out.println( $first );
end

Hi Laune,
Vehicles list contains the values name and qty and the values are
car,10
jeep,20
lorry,30
car,30
Below is my implementation for that scenario which i have asked.
rule "HelloWorld_13"
salience 65523
when
$p1:Policy()
$trandet:Vehicle(name in ("CAR")) from $p1.vehicleslist
then
System.out.println($trandet.getQty());
end
The result for the above rule is
30
10
but i need 10 alone which is at the top of that list.. is that possible.?
and when googling found that if we use salience along with 'from' its
possible..
Please share your thoughts on the above.
Thanks
Salt
