Method Detail
-
now
public static BritishCutoverDate now()
Obtains the currentBritishCutoverDate
from the system clock in the default time-zone.This will query the
system clock
in the default time-zone to obtain the current date.Using this method will prevent the ability to use an alternate clock for testing because the clock is hard-coded.
- Returns:
- the current date using the system clock and default time-zone, not null
-
now
public static BritishCutoverDate now(ZoneId zone)
Obtains the currentBritishCutoverDate
from the system clock in the specified time-zone.This will query the
system clock
to obtain the current date. Specifying the time-zone avoids dependence on the default time-zone.Using this method will prevent the ability to use an alternate clock for testing because the clock is hard-coded.
- Parameters:
zone
- the zone ID to use, not null- Returns:
- the current date using the system clock, not null
-
now
public static BritishCutoverDate now(Clock clock)
Obtains the currentBritishCutoverDate
from the specified clock.This will query the specified clock to obtain the current date - today. Using this method allows the use of an alternate clock for testing. The alternate clock may be introduced using dependency injection.
- Parameters:
clock
- the clock to use, not null- Returns:
- the current date, not null
- Throws:
DateTimeException
- if the current date cannot be obtained
-
of
public static BritishCutoverDate of(int prolepticYear, int month, int dayOfMonth)
Obtains aBritishCutoverDate
representing a date in the British Cutover calendar system from the proleptic-year, month-of-year and day-of-month fields.This returns a
BritishCutoverDate
with the specified fields.Dates in the middle of the cutover gap, such as the 10th September 1752, will not throw an exception. Instead, the date will be treated as a Julian date and converted to an ISO date, with the day of month shifted by 11 days.
Invalid dates, such as September 31st will throw an exception.
- Parameters:
prolepticYear
- the British Cutover proleptic-yearmonth
- the British Cutover month-of-year, from 1 to 12dayOfMonth
- the British Cutover day-of-month, from 1 to 31- Returns:
- the date in British Cutover calendar system, not null
- Throws:
DateTimeException
- if the value of any field is out of range, or if the day-of-month is invalid for the month-year
-
from
public static BritishCutoverDate from(TemporalAccessor temporal)
Obtains aBritishCutoverDate
from a temporal object.This obtains a date in the British Cutover calendar system based on the specified temporal. A
TemporalAccessor
represents an arbitrary set of date and time information, which this factory converts to an instance ofBritishCutoverDate
.The conversion uses the
EPOCH_DAY
field, which is standardized across calendar systems.This method matches the signature of the functional interface
TemporalQuery
allowing it to be used as a query via method reference,BritishCutoverDate::from
.- Parameters:
temporal
- the temporal object to convert, not null- Returns:
- the date in British Cutover calendar system, not null
- Throws:
DateTimeException
- if unable to convert to aBritishCutoverDate
-
rangeChrono
public ValueRange rangeChrono(ChronoField field)
-
getChronology
public BritishCutoverChronology getChronology()
Gets the chronology of this date, which is the British Cutover calendar system.The
Chronology
represents the calendar system in use. The era and other fields inChronoField
are defined by the chronology.- Specified by:
getChronology
in interfaceChronoLocalDate
- Returns:
- the British Cutover chronology, not null
-
getEra
public JulianEra getEra()
Gets the era applicable at this date.The British Cutover calendar system has two eras, 'AD' and 'BC', defined by
JulianEra
.- Specified by:
getEra
in interfaceChronoLocalDate
- Returns:
- the era applicable at this date, not null
-
lengthOfMonth
public int lengthOfMonth()
Returns the length of the month represented by this date.This returns the length of the month in days. This takes into account the cutover, returning 19 in September 1752.
- Specified by:
lengthOfMonth
in interfaceChronoLocalDate
- Returns:
- the length of the month in days, from 19 to 31
-
lengthOfYear
public int lengthOfYear()
Returns the length of the year represented by this date.This returns the length of the year in days. This takes into account the cutover, returning 355 in 1752.
- Specified by:
lengthOfYear
in interfaceChronoLocalDate
- Returns:
- the length of the month in days, from 19 to 31
