Class YearMonthDay

  • All Implemented Interfaces:
    java.io.Serializable, java.lang.Comparable<ReadablePartial>, ReadablePartial

    @Deprecated
    public final class YearMonthDay
    extends BasePartial
    implements ReadablePartial, java.io.Serializable
    Deprecated.
    Use LocalDate which has a much better internal implementation and has been available since 1.3
    YearMonthDay is an immutable partial supporting the year, monthOfYear and dayOfMonth fields.

    NOTE: This class only supports the three fields listed above. Thus, you cannot query the dayOfWeek or centuryOfEra fields for example. The new LocalDate class removes this restriction.

    Calculations on YearMonthDay are performed using a Chronology. This chronology is set to be in the UTC time zone for all calculations.

    Each individual field can be queried in two ways:

    • getMonthOfYear()
    • monthOfYear().get()
    The second technique also provides access to other useful methods on the field:
    • numeric value - monthOfYear().get()
    • text value - monthOfYear().getAsText()
    • short text value - monthOfYear().getAsShortText()
    • maximum/minimum values - monthOfYear().getMaximumValue()
    • add/subtract - monthOfYear().addToCopy()
    • set - monthOfYear().setCopy()

    YearMonthDay is thread-safe and immutable, provided that the Chronology is as well. All standard Chronology classes supplied are thread-safe and immutable.

    • Constructor Detail

      • YearMonthDay

        public YearMonthDay()
        Deprecated.
        Constructs a YearMonthDay with the current date, using ISOChronology in the default zone to extract the fields.

        The constructor uses the default time zone, resulting in the local time being initialised. Once the constructor is complete, all further calculations are performed without reference to a timezone (by switching to UTC).

      • YearMonthDay

        public YearMonthDay​(DateTimeZone zone)
        Deprecated.
        Constructs a YearMonthDay with the current date, using ISOChronology in the specified zone to extract the fields.

        The constructor uses the specified time zone to obtain the current date. Once the constructor is complete, all further calculations are performed without reference to a timezone (by switching to UTC).

        Parameters:
        zone - the zone to use, null means default zone
        Since:
        1.1

        Deprecated.
        Constructs a YearMonthDay with the current date, using the specified chronology and zone to extract the fields.

        The constructor uses the time zone of the chronology specified. Once the constructor is complete, all further calculations are performed without reference to a timezone (by switching to UTC).

        Deprecated.
        Constructs a YearMonthDay extracting the partial fields from the specified milliseconds using the ISOChronology in the default zone.

        The constructor uses the default time zone, resulting in the local time being initialised. Once the constructor is complete, all further calculations are performed without reference to a timezone (by switching to UTC).

        Parameters:
        instant - the milliseconds from 1970-01-01T00:00:00Z
      • YearMonthDay

        Constructs a YearMonthDay extracting the partial fields from the specified milliseconds using the chronology provided.

        The constructor uses the time zone of the chronology specified. Once the constructor is complete, all further calculations are performed without reference to a timezone (by switching to UTC).

        Parameters:

        public YearMonthDay​(java.lang.Object instant)
        Deprecated.
        Constructs a YearMonthDay from an Object that represents a time.

        The recognised object types are defined in ConverterManager and include ReadableInstant, String, Calendar and Date. The String formats are described by ISODateTimeFormat.dateOptionalTimeParser().

        The chronology used will be derived from the object, defaulting to ISO.

        NOTE: Prior to v1.3 the string format was described by ISODateTimeFormat.dateTimeParser(). Time only strings are now rejected.

        Parameters:
        instant - the datetime object, null means now
        Throws:
        java.lang.IllegalArgumentException - if the instant is invalid

      • fromCalendarFields

        public static YearMonthDay fromCalendarFields​(java.util.Calendar calendar)
        Deprecated.
        Constructs a YearMonthDay from a java.util.Calendar using exactly the same field values avoiding any time zone effects.

        Each field is queried from the Calendar and assigned to the YearMonthDay. This is useful if you have been using the Calendar as a local date, ignoring the zone.

        This factory method ignores the type of the calendar and always creates a YearMonthDay with ISO chronology. It is expected that you will only pass in instances of GregorianCalendar however this is not validated.

        Parameters:
        calendar - the Calendar to extract fields from
        Returns:
        the created YearMonthDay
        Throws:
        java.lang.IllegalArgumentException - if the calendar is null
        java.lang.IllegalArgumentException - if the date is invalid for the ISO chronology
        Since:
        1.2
      • fromDateFields

        Constructs a YearMonthDay from a java.util.Date using exactly the same field values avoiding any time zone effects.

        Each field is queried from the Date and assigned to the YearMonthDay. This is useful if you have been using the Date as a local date, ignoring the zone.

        This factory method always creates a YearMonthDay with ISO chronology.

        Parameters:
        date - the Date to extract fields from
        Returns:
        the created YearMonthDay
        Throws:
        java.lang.IllegalArgumentException - if the calendar is null
        java.lang.IllegalArgumentException - if the date is invalid for the ISO chronology
        Since:
        1.2

      • withChronologyRetainFields

        public YearMonthDay withChronologyRetainFields​(Chronology newChronology)
        Deprecated.
        Returns a copy of this date with the specified chronology. This instance is immutable and unaffected by this method call.

        This method retains the values of the fields, thus the result will typically refer to a different instant.

        The time zone of the specified chronology is ignored, as YearMonthDay operates without a time zone.

        Parameters:
        newChronology - the new chronology, null means ISO
        Returns:
        a copy of this datetime with a different chronology

        Deprecated.
        Returns a copy of this date with the specified field set to a new value.

        For example, if the field type is dayOfMonth then the day would be changed in the returned instance.

        These three lines are equivalent:

         YearMonthDay updated = ymd.withField(DateTimeFieldType.dayOfMonth(), 6);
         YearMonthDay updated = ymd.dayOfMonth().setCopy(6);
         YearMonthDay updated = ymd.property(DateTimeFieldType.dayOfMonth()).setCopy(6);
         
        Parameters:
        fieldType - the field type to set, not null
        value - the value to set
        Returns:
        a copy of this instance with the field set
        Throws:
        java.lang.IllegalArgumentException - if the value is null or invalid

        Deprecated.
        Returns a copy of this date with the value of the specified field increased.

        If the addition is zero, then this is returned.

         YearMonthDay added = ymd.plusDays(6);
         YearMonthDay added = ymd.dayOfMonth().addToCopy(6);
         
        Parameters:

                                            int scalar)
        Deprecated.
        Returns a copy of this date with the specified period added.

        If the addition is zero, then this is returned. Fields in the period that aren't present in the partial are ignored.
