Enum ZoneOffsetTransitionRule.TimeDefinition

  • All Implemented Interfaces:
    java.io.Serializable, java.lang.Comparable<ZoneOffsetTransitionRule.TimeDefinition>
    Enclosing class:
    ZoneOffsetTransitionRule

    public static enum ZoneOffsetTransitionRule.TimeDefinition
    extends java.lang.Enum<ZoneOffsetTransitionRule.TimeDefinition>
    A definition of the way a local time can be converted to the actual transition date-time.

    Time zone rules are expressed in one of three ways:

    • Relative to UTC
    • Relative to the standard offset in force
    • Relative to the wall offset (what you would see on a clock on the wall)

    • Enum Constant Summary

      Enum Constants 
      Enum Constant Description
      STANDARD
      The local date-time is expressed in terms of the standard offset.
      UTC
      The local date-time is expressed in terms of the UTC offset.
      WALL
      The local date-time is expressed in terms of the wall offset.
    • Method Detail

      • values

        public static ZoneOffsetTransitionRule.TimeDefinition[] 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 (ZoneOffsetTransitionRule.TimeDefinition c : ZoneOffsetTransitionRule.TimeDefinition.values())
            System.out.println(c);
        
        Returns:
        an array containing the constants of this enum type, in the order they are declared
      • valueOf

        public static ZoneOffsetTransitionRule.TimeDefinition valueOf​(java.lang.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:
        java.lang.IllegalArgumentException - if this enum type has no constant with the specified name
        java.lang.NullPointerException - if the argument is null
      • createDateTime

        public LocalDateTime createDateTime​(LocalDateTime dateTime,
                                            ZoneOffset standardOffset,
                                            ZoneOffset wallOffset)
        Converts the specified local date-time to the local date-time actually seen on a wall clock.

        This method converts using the type of this enum. The output is defined relative to the 'before' offset of the transition.

        The UTC type uses the UTC offset. The STANDARD type uses the standard offset. The WALL type returns the input date-time. The result is intended for use with the wall-offset.

        Parameters:
        dateTime - the local date-time, not null
        standardOffset - the standard offset, not null
        wallOffset - the wall offset, not null
        Returns:
        the date-time relative to the wall/before offset, not null
