[rules-users] Getting Latest Matching Fact

[Wolfgang Laun]

Put this code into method of Policy with the signature

   List<Vehicle> getValidAB()

where the returned List either contains the element you want or is
empty. Then you can write

rule "find first 'car'"
when
    $p1:Policy()
    $carList: List( size > 0 )
        from collect ( Vehicle( name ==  "car" )
            from $p1.getValidAB() )
    $first: Vehicle( ) from $carList.get( 0 )
then
    System.out.println( $first );
end
