Subject [jexl] - Jexl parser tree - retrieve variables from expression
Date Tue, 20 Jun 2017 01:42:50 GMT
JEXL question: 

Is there a way to take an expression such as “(x + y) / z)”  and get a parser tree or
even just a list of the variables in the expression?

I would like to know what variables are in my expression, in the example above, I would want
a list of x,y,z

Is that possible?
