public final class ThaiBuddhistChronology extends Chronology implements Serializable
This chronology defines the rules of the Thai Buddhist calendar system.
This calendar system is primarily used in Thailand.
Dates are aligned such that 2484-01-01 (Buddhist)
is 1941-01-01 (ISO)
.
The fields are defined as follows:
Modifier and Type | Field and Description |
---|---|
static ThaiBuddhistChronology |
INSTANCE
Singleton instance of the Buddhist chronology.

public String getId()
The ID uniquely identifies the Chronology
.
It can be used to lookup the Chronology
using Chronology.of(String)
.
getId

getCalendarType()
public String getCalendarType()
The calendar type is an identifier defined by the
Unicode Locale Data Markup Language (LDML) specification.
It can be used to lookup the Chronology
using Chronology.of(String)
.
It can also be used as part of a locale, accessible via
Locale.getUnicodeLocaleType(String)
with the key 'ca'.

Chronology
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.
This implementation uses Chronology.dateNow(Clock)
.
dateNow
in class Chronology
public ThaiBuddhistDate dateNow(ZoneId zone)
Chronology
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.
dateNow
in class Chronology
zone
- the zone ID to use, not nullpublic ThaiBuddhistDate dateNow(Clock clock)
Chronology
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
.
dateNow
in class Chronology
clock
- the clock to use, not nullpublic ThaiBuddhistDate date(TemporalAccessor temporal)
Chronology
This obtains a date in this chronology based on the specified temporal.
A TemporalAccessor
represents an arbitrary set of date and time information,
which this factory converts to an instance of ChronoLocalDate
.
The conversion typically 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, aChronology::date
.
date

temporal

public ChronoLocalDateTime<ThaiBuddhistDate> localDateTime(TemporalAccessor temporal)
Chronology
This obtains a date-time in this chronology based on the specified temporal.
A TemporalAccessor
represents an arbitrary set of date and time information,
which this factory converts to an instance of ChronoLocalDateTime
.
The conversion extracts and combines the ChronoLocalDate
and the
LocalTime
from the temporal object.
Implementations are permitted to perform optimizations such as accessing
those fields that are equivalent to the relevant objects.
The result uses this chronology.
This method matches the signature of the functional interface TemporalQuery
allowing it to be used as a query via method reference, aChronology::localDateTime

temporal

public ChronoZonedDateTime<ThaiBuddhistDate> zonedDateTime(TemporalAccessor temporal)
Chronology
ChronoZonedDateTime
in this chronology from another temporal object.
This obtains a zoned date-time in this chronology based on the specified temporal.
A TemporalAccessor
represents an arbitrary set of date and time information,
which this factory converts to an instance of ChronoZonedDateTime
.
The conversion will first obtain a ZoneId
from the temporal object,
falling back to a ZoneOffset
if necessary. It will then try to obtain
an Instant
, falling back to a ChronoLocalDateTime
if necessary.
The result will be either the combination of ZoneId
or ZoneOffset
with Instant
or ChronoLocalDateTime
.
Implementations are permitted to perform optimizations such as accessing
those fields that are equivalent to the relevant objects.
The result uses this chronology.
This method matches the signature of the functional interface TemporalQuery

public ChronoZonedDateTime<ThaiBuddhistDate> zonedDateTime(Instant instant, ZoneId zone)
Chronology
ChronoZonedDateTime
in this chronology from an Instant
.
This obtains a zoned date-time with the same instant as that specified.
zonedDateTime
in class Chronology
instant
- the instant to create the date-time from, not nullzone
- the time-zone, not nullpublic boolean isLeapYear(long prolepticYear)
Thai Buddhist leap years occur exactly in line with ISO leap years. This method does not validate the year passed in, and only has a well-defined result for years in the supported range.
isLeapYear
in class Chronology
prolepticYear
- the proleptic-year to check, not validated for rangepublic int prolepticYear(Era era, int yearOfEra)
Chronology
This combines the era and year-of-era into the single proleptic-year field.
If the chronology makes active use of eras, such as JapaneseChronology
then the year-of-era will be validated against the era.
For other chronologies, validation is optional.
prolepticYear
in class Chronology
era
- the era of the correct type for the chronology, not nullyearOfEra
- the chronology year-of-erapublic Era eraOf(int eraValue)
Chronology
The era is, conceptually, the largest division of the time-line. Most calendar systems have a single epoch dividing the time-line into two eras. However, some have multiple eras, such as one for the reign of each leader. The exact meaning is determined by the chronology according to the following constraints.
The era in use at 1970-01-01 must have the value 1. Later eras must have sequentially higher values. Earlier eras must have sequentially lower values. Each chronology must refer to an enum or similar singleton to provide the era values.
This method returns the singleton era of the correct type for the specified era value.
eraOf
in class Chronology
eraValue
- the era valuepublic List<Era> eras()
Chronology
Most calendar systems have an era, within which the year has meaning. If the calendar system does not support the concept of eras, an empty list must be returned.
eras
in class Chronology
public ValueRange range(ChronoField field)
Chronology
All fields can be expressed as a long
integer.
This method returns an object that describes the valid range for that value.
Note that the result only describes the minimum and maximum valid values and it is important not to read too much into them. For example, there could be values within the range that are invalid for the field.
This method will return a result whether or not the chronology supports the field.
range
in class Chronology
field
- the field to get the range for, not null
