Henri Biestro commented on JEXL-428:
------------------------------------
The difficulty might be in respecting the expectation :{code}compare(x, y) ==
-compare(y, x){code}
The lengthy workaround would be to implement the operator methods in the
JexlArithmetic with the intended signature (public boolean lessThan(XuClass xu,
String right); public boolean greaterThan(String right, XuClass xu); etc.).
As an improvement, it could be possible to expose a compare operator
(JexlOperator.COMPARE) to only have to implement 2 methods.

> I defined a Class with implemented Comparable interface, when compare it with
> a string object, engine does not call the compareTo method but compares by
> string value.
>
> At JexlArithmetic.java L787, if one of the left/right value is string type,
> then compares by string value, I think if the left value is Comparable and
> not String type, using left object's compareTo method first makes more sense.
> Thanks!
