If a type used in ConfigurationKey type argument implements this interface, it is expected to provide the following three static methods: 
    

  • public static SELF valueOf(String value)

  • public static String description()

  • public static String exampleValue()

 None of them should throw checked exceptions. Based on these methods, an instance of ConfigurationValueParser is created and used by the configuration system.
