    • Method Detail

      • values

        public static NullPrecedence[] values()
        Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:
        for (NullPrecedence c : NullPrecedence.values())
            System.out.println(c);
        
        Returns:
        an array containing the constants of this enum type, in the order they are declared
      • valueOf

        public static NullPrecedence valueOf​(String name)
        Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)
        Parameters:
        name - the name of the enum constant to be returned.
        Returns:
        the enum constant with the specified name
        Throws:
        IllegalArgumentException - if this enum type has no constant with the specified name
        NullPointerException - if the argument is null
      • isDefaultOrdering

        public boolean isDefaultOrdering​(SortDirection sortOrder,
                                         NullOrdering nullOrdering)
        Is this null precedence the default for the given sort order and null ordering.
      • parse

        public static NullPrecedence parse​(String name)
        Interprets a string representation of a NullPrecedence, returning null by default. For alternative default handling, see parse(String, NullPrecedence)
        Parameters:
        name - The String representation to interpret
        Returns:
        The recognized NullPrecedence, or null
      • parse

        public static NullPrecedence parse​(String name,
                                           NullPrecedence defaultValue)
        Interprets a string representation of a NullPrecedence, returning the specified default if not recognized.
        Parameters:
        name - The String representation to interpret
        defaultValue - The default value to use
        Returns:
        The recognized NullPrecedence, or defaultValue.
