    - #### createPropertiesReader

          public PropertiesConfiguration.PropertiesReader createPropertiesReader(Reader in)

      Description copied from interface: `PropertiesConfiguration.IOFactory`
      Creates a `PropertiesReader` for reading a properties file. This method is called whenever the `PropertiesConfiguration` is loaded. The reader returned by this method is then used for parsing the properties file.
      Specified by:
        `createPropertiesReader` in interface `PropertiesConfiguration.IOFactory`
      Parameters:
        `in` - the underlying reader (of the properties file)
      Returns:
        the `PropertiesReader` for loading the configuration

    - #### createPropertiesWriter

          public PropertiesConfiguration.PropertiesWriter createPropertiesWriter(Writer out,
                                                                                 ListDelimiterHandler handler)

      Description copied from interface: `PropertiesConfiguration.IOFactory`
      Creates a `PropertiesWriter` for writing a properties file. This method is called before the `PropertiesConfiguration` is saved. The writer returned by this method is then used for writing the properties file.
      Specified by:
        `createPropertiesWriter` in interface `PropertiesConfiguration.IOFactory`
      Parameters:
        `out` - the underlying writer (to the properties file)
        `handler` - the list delimiter delimiter for list parsing
      Returns:
        the `PropertiesWriter` for saving the configuration
