Hi,
Yep, this can be done with the following:-
rule "largest X"
when
X ( $v : value )
not X (value > $v)
then
// $v is the maximum
end
rule "lowest X"
when
X ( $v : value )
not X (value < $v)
then
// $v is the minimum
There are more examples on the wiki.
Cheers,
Mike

Subject: [rules-users] Querying for a particular object from working memory
Hi,
Is there a way to query for an object of type X among a pool of objects of
type X in working memory that have the maximum/minimum value of a
particular attribute a1 ?
For example
if I have a class C
Class C {
int a1;
int a2;
}
As part of my rules evaluataion I have N instances of C inserted into
working memory c1,c2.....cn. Now I would like to query for the object that
the max value of attribute a1
Is this possible?
Thanks
Jai
