Dear all,

here is my problem/question.

In the controller (extension) of one of my pages, I get an expression in a String variable. 

I would like to know if the re is any solution for me to evaluate this expression from the String.

Let's say I get something like this:

String s = '(true AND false) OR true';

Is there any function (like the eval javascript function) that would allow me to evaluate my expression?

Boolean ret = eval(s); // true

Thank you everyone in advance.
