Dmitri Blinov commented on JEXL-243: ------------------------------------ Well, this is basically works, the only thing is what if I have in one framework two different types of scripts, say scripts with side effects and scripts without side effects (or better to name them getters and setters). Those types of scripts are supposed to use a single Jexl engine instance. It would be more practical to be able to specify desired features right to JexlEngine.createScript() method. Maybe JexlEngine.createExpression() should get such an overload too, but maybe it's even better, not to speak of backward compatibility now, to have the only one JexlEngine.createScript() which could create both "scripts" and "expressions" by simply specifying "right" feature sets in each case. > Allow restricting available features in Script/Expressions > ---------------------------------------------------------- > > Key: JEXL-243 > URL: https://issues.apache.org/jira/browse/JEXL-243 > Project: Commons JEXL > Issue Type: Improvement > Affects Versions: 3.1 > Reporter: Henri Biestro > Assignee: Henri Biestro > Fix For: 3.2 > > > Restrict features related to potential dangers/difficulties one may encounter > whilst scripting; > Reserved Names: a set of reserved variable names that can not be used as > local variable (or parameter) names > Registers: boolean property allowing parsing of register syntax (#number) > Global Side Effect : boolean property controlling assigning/modifying values > on global variables > Side Effect: boolean property controlling side effects assigning/modifying > values on any variable > New Instance: boolean property controlling creating new instances through > new(...) or using class as functor > Loops: boolean property controlling usage of loop constructs (while(true), > for(...)) > Lambda: boolean property controlling usage of script function declarations > -- This message was sent by Atlassian JIRA (v6.4.14#64029)
