          public JexlScriptObject()

  - ### Method Detail

    - #### 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.

      Returns:
        the shared underlying JEXL engine

    - #### getOut

          public PrintWriter getOut()

      Gives access to the engine scope output writer (defaults to System.out).
      Returns:
        the engine output writer

    - #### getErr

          public PrintWriter getErr()

      Gives access to the engine scope error writer (defaults to System.err).
      Returns:
        the engine error writer

    - #### getIn

          public Reader getIn()

      Gives access to the engine scope input reader (defaults to System.in).
      Returns:
        the engine input reader

    - #### getSystem

          public Class<System> getSystem()

      Gives access to System class.
      Returns:
        System.class

    - #### getLogger

          public org.apache.commons.logging.Log getLogger()

      Gives access to the engine logger.
      Returns:
        the JexlScriptEngine logger
