[rules-users] Less than "<" greater than ">" operator

[Bruno Freudensprung]

Hi,

 From what I see in the code 
("org.drools.base.evaluators.ComparableEvaluatorsDefinition" class), 
comparison operators have different implementations depending on the 
type of the arguments. For Integer, it uses the intValue() and the < 
operator. There a many pre-defined type but, in the end, the Object type 
seems to be implemented by casting arguments to "Comparable" then using 
the compareTo() method.

Bruno.
