  - ### getEngine

    public JexlEngine getEngine()
    Gives access to the underlying JEXL engine shared between all ScriptEngine instances.

    Although this allows to manipulate various engine flags (lenient, debug, cache...) for all JexlScriptEngine instances, you probably should only do so if you are in strict control and sole user of the JEXL scripting feature.

      the shared underlying JEXL engine
