  - ### Method Detail

    - #### getAllow

          public String getAllow()

      Return a string representation of the `NetMask` list in #allow.
      Overrides:
        `getAllow` in class `RequestFilterValve`
      Returns:
        the #allow list as a string, without the leading '[' and trailing ']'

    - #### setAllow

          public void setAllow​(String input)

      Fill the #allow list with the list of netmasks provided as an argument, if any. Calls #fillFromInput.
      Overrides:
        `setAllow` in class `RequestFilterValve`
      Parameters:
        `input` - The list of netmasks, as a comma separated string
      Throws:
        `IllegalArgumentException` - One or more netmasks are invalid

    - #### getDeny

          public String getDeny()

      Return a string representation of the `NetMask` list in #deny.
      Overrides:
        `getDeny` in class `RequestFilterValve`
      Returns:
        the #deny list as a string, without the leading '[' and trailing ']'

    - #### setDeny

          public void setDeny​(String input)

      Fill the #deny list with the list of netmasks provided as an argument, if any. Calls #fillFromInput.
      Overrides:
        `setDeny` in class `RequestFilterValve`
      Parameters:
        `input` - The list of netmasks, as a comma separated string
      Throws:
        `IllegalArgumentException` - One or more netmasks are invalid

    - #### invoke

          public void invoke​(Request request,
                             Response response)
                      throws IOException,
                             ServletException

      Description copied from class: `RequestFilterValve`
      Extract the desired request property, and pass it (along with the specified request and response objects) to the protected `process()` method to perform the actual filtering. This method must be implemented by a concrete subclass.
      Specified by:
        `invoke` in interface `Valve`
      Specified by:
        `invoke` in class `RequestFilterValve`
      Parameters:
        `request` - The servlet request to be processed
        `response` - The servlet response to be created
      Throws:
        `IOException` - if an input/output error occurs
        `ServletException` - if a servlet error occurs

    - #### isAllowed

          public boolean isAllowed​(String property)

      Description copied from class: `RequestFilterValve`
      Perform the test implemented by this Valve, matching against the specified request property value. This method is public so that it can be called through JMX, e.g. to test whether certain IP address is allowed or denied by the valve configuration.
      Overrides:
        `isAllowed` in class `RequestFilterValve`
      Parameters:
        `property` - The request property value on which to filter
      Returns:
        `true` if the request is allowed

    - #### getLog

          protected Log getLog()

      Specified by:
        `getLog` in class `RequestFilterValve`
