所有已实现的接口:

Serializable

public final class JulianChronology
extends AssembledChronology

Implements a pure proleptic Julian calendar system, which defines every fourth year as leap. This implementation follows the leap year rule strictly, even for dates before 8 CE, where leap years were actually irregular. In the Julian calendar, year zero does not exist: 1 BCE is followed by 1 CE.

Although the Julian calendar did not exist before 45 BCE, this chronology assumes it did, thus it is proleptic. This implementation also fixes the start of the year at January 1.

JulianChronology is thread-safe and immutable.

方法详细资料

getInstanceUTC

public static JulianChronology getInstanceUTC()

Gets an instance of the JulianChronology. The time zone of the returned instance is UTC.

返回:

a singleton UTC instance of the chronology

getInstance

public static JulianChronology getInstance()

Gets an instance of the JulianChronology in the default time zone.

返回:

a chronology in the default time zone

getInstance

public static JulianChronology getInstance(DateTimeZone zone)

Gets an instance of the JulianChronology in the given time zone.

参数:

zone - the time zone to get the chronology in, null is default

返回:

a chronology in the specified time zone

getInstance

public static JulianChronology getInstance(DateTimeZone zone,
                                           int minDaysInFirstWeek)

Gets an instance of the JulianChronology in the given time zone.

参数:

zone - the time zone to get the chronology in, null is default

minDaysInFirstWeek - minimum number of days in first week of the year; default is 4

返回:

a chronology in the specified time zone

withUTC

public Chronology withUTC()

Gets the Chronology in the UTC time zone.

指定者:

withUTC 在类中 BaseChronology

返回:

the chronology in UTC

withZone

public Chronology withZone(DateTimeZone zone)

Gets the Chronology in a specific time zone.

指定者:

withZone 在类中 BaseChronology

参数:

zone - the zone to get the chronology in, null is default

返回:

the chronology

ZonedChronology

assemble

protected void assemble(AssembledChronology.Fields fields)

从类复制的说明: AssembledChronology

Invoked by the constructor and after deserialization to allow subclasses to define all of its supported fields. All unset fields default to unsupported instances.

参数:

fields - container of fields

getZone

public DateTimeZone getZone()

从类复制的说明: BaseChronology

Returns the DateTimeZone that this Chronology operates in, or null if unspecified.

覆盖:

getZone 在类中 AssembledChronology

返回:

DateTimeZone null if unspecified

getDateTimeMillis

public long getDateTimeMillis(int year,
                              int monthOfYear,
                              int dayOfMonth,
                              int millisOfDay)
                       throws IllegalArgumentException

从类复制的说明: BaseChronology

Returns a datetime millisecond instant, formed from the given year, month, day, and millisecond values. The set of given values must refer to a valid datetime, or else an IllegalArgumentException is thrown.

The default implementation calls upon separate DateTimeFields to determine the result. Subclasses are encouraged to provide a more efficient implementation.

覆盖:

getDateTimeMillis 在类中 AssembledChronology

参数:

year - year to use

monthOfYear - month to use

dayOfMonth - day of month to use

millisOfDay - millisecond to use

返回:

millisecond instant from 1970-01-01T00:00:00Z

抛出:

IllegalArgumentException - if the values are invalid

getDateTimeMillis

public long getDateTimeMillis(int year,
                              int monthOfYear,
