[rules-users] Use of the binding variable

[Esteban Aliverti]

What you have described is half of the usage of binding variables. You can
bind a variable to a fact or to individual fields of a fact. You can then
use those variables in the LHS or the RHS of your rules.
For example:

1.- Find different Person objects

when
  $p1: Person($name1: name)
  $p2: Person($name2: name, *this != $p1*)
then
  System.out.println("Found "+$p1+" with name '"+$name1+"' and "+$p2+" with
name '"+$name2+"'");
end

Regards,
