      Constructor.

  • Method Details

    • readResolve

      private Object readResolve()

    • derive

      protected DayOfWeek derive(Calendrical calendrical)
      Description copied from class: CalendricalRule
      Derives the value of this rule from a calendrical.

      This method derives the value for this field from other fields in the calendrical without directly querying the calendrical for the value.

      For example, if this field is quarter-of-year, then the value can be derived from month-of-year.

      The implementation only needs to derive the value based on its immediate parents. The use of Calendrical.get(CalendricalRule) will extract any further parents on demand.

      A typical implementation of this method obtains the parent value and performs a calculation. For example, here is a simple implementation for the quarter-of-year field: 

      Integer moyVal = calendrical.get(ISOChronology.monthOfYearRule());
return (moyVal != null ? ((moyVal - 1) % 4) + 1) : null;

      This method is designed to be overridden in subclasses. The subclass implementation must be thread-safe. The subclass implementation must not request the value of this rule from the specified calendrical, otherwise a stack overflow error will occur.

      Overrides:
      derive in class CalendricalRule<DayOfWeek>
      Parameters:
      calendrical - the calendrical to derive from, not null
      Returns:
      the derived value, null if unable to derive

    • convertValueToInt

      public int convertValueToInt(DayOfWeek value)
      Description copied from class: DateTimeFieldRule
      Converts the typed value of the rule to the int equivalent.

      This default implementation handles Integer and Enum. When the reified type is another type, this method must be overridden.

      Overrides:
      convertValueToInt in class DateTimeFieldRule<DayOfWeek>
      Parameters:
      value - the value to convert, not null
      Returns:
      the int value of the field

    • convertIntToValue

      public DayOfWeek convertIntToValue(int value)
      Description copied from class: DateTimeFieldRule
      Converts the int to a typed value of the rule.

      The int will be checked to ensure that it is within the valid range of values for the field.

      This default implementation handles Integer and Enum. When the reified type is another type, this method must be overridden.

      Overrides:
      convertIntToValue in class DateTimeFieldRule<DayOfWeek>
      Parameters:
      value - the value to convert, not null
      Returns:
      the int value of the field

    • interpret

      protected DayOfWeek interpret(CalendricalMerger merger, Object value)
      Description copied from class: CalendricalRule
      Interprets the specified value converting it into an in range value of the correct type for this rule.

      Before this method is called, the value will be checked to ensure it is not of the type of this rule.

      Overrides:
      interpret in class CalendricalRule<DayOfWeek>
      Parameters:
      merger - the merger instance controlling the merge process, not null
      value - the value to interpret, null if unable to interpret the value
      Returns:
      the interpreted value

    • createTextStores

      protected void createTextStores(EnumMap<DateTimeFormatterBuilder.TextStyle, DateTimeFieldRule.TextStore> textStores, Locale locale)
      Description copied from class: DateTimeFieldRule
      Creates the text store for each style for the specified locale.

      It is intended that a new copy of the text store should be created in response to calling this method as the result is cached by DateTimeFieldRule.getTextStore(Locale, DateTimeFormatterBuilder.TextStyle).

      Overrides:
      createTextStores in class DateTimeFieldRule<DayOfWeek>
      Parameters:
      textStores - the map to populate with TextStore instances, not null
      locale - the locale to use, not null
