Assuming you are using 4.0, just bind one and compare to the other:
rule XXX
when
Tree( $new : newNumberLeaves, oldNumberLeaves > $new )
then
// do something
end

Hi all,
I'd like to make a comparison of two attributes on the same object, but
would like to do it in one line to facilitate easy DSL.
Example:
Class Tree{
int oldNumberLeaves;
int newNumberLeaves;
}
What I'd like to say is "when the oldNumberLeaves > newNumberLeaves
then...."
Can anyone give me a tip on this one?
Thanks much,
Rick
