      • stringToValue

        public java.lang.Boolean stringToValue​(java.lang.String txt)
                                        throws ConfigException
        Description copied from class: ConfigKey
        Decodes a string value to the value type of this key. An empty string should be interpreted as a null value, but this may cause an exception if null is not a permissible value for this key.
        Specified by:
        stringToValue in class ConfigKey<java.lang.Boolean>
        Parameters:
        txt - string representation of value
        Returns:
        value
        Throws:
        ConfigException
      • valueToString

        public java.lang.String valueToString​(java.lang.Boolean value)
        Description copied from class: ConfigKey
        Reports a value as a string. If at all possible the roundtripping should be possible, so stringToValue(valueToString(v)).equals(v). A null value, if permitted, should be represented as an empty string.
        Specified by:
        valueToString in class ConfigKey<java.lang.Boolean>
        Parameters:
        value - possible value associated with this key
        Returns:
        string representation
