public final class ThaiBuddhistChronology extends Chronology implements Serializable
The Thai Buddhist calendar system.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)
is1941-01-01 (ISO)
.The fields are defined as follows:
- era - There are two eras, the current 'Buddhist' (BE) and the previous era (BEFORE_BE).
- year-of-era - The year-of-era for the current era increases uniformly from the epoch at year one. For the previous era the year increases from one as time goes backwards. The value for the current era is equal to the ISO proleptic-year plus 543.
- proleptic-year - The proleptic year is the same as the year-of-era for the current era. For the previous era, years have zero, then negative values. The value is equal to the ISO proleptic-year plus 543.
- month-of-year - The ThaiBuddhist month-of-year exactly matches ISO.
- day-of-month - The ThaiBuddhist day-of-month exactly matches ISO.
- day-of-year - The ThaiBuddhist day-of-year exactly matches ISO.
- leap-year - The ThaiBuddhist leap-year pattern exactly matches ISO, such that the two calendars are never out of step.

dateNow
public ThaiBuddhistDate dateNow()
Description copied from class:Chronology
Obtains the current local date in this chronology 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.
This implementation uses
Chronology.dateNow(Clock)
.- Overrides:
dateNow
in classChronology
- Returns:
- the current local date using the system clock and default time-zone, not null
-
dateNow
public ThaiBuddhistDate dateNow(ZoneId zone)
Description copied from class:Chronology
Obtains the current local date in this chronology 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.
- Overrides:
dateNow
in classChronology
- Parameters:
zone
- the zone ID to use, not null- Returns:
- the current local date using the system clock, not null
-
dateNow
public ThaiBuddhistDate dateNow(Clock clock)
Description copied from class:Chronology
Obtains the current local date in this chronology 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
.- Overrides:
dateNow
in classChronology
- Parameters:
clock
- the clock to use, not null- Returns:
- the current local date, not null
-
isLeapYear
public boolean isLeapYear(long prolepticYear)
Checks if the specified year is a leap year.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.
- Specified by:
isLeapYear
in classChronology
- Parameters:
prolepticYear
- the proleptic-year to check, not validated for range- Returns:
- true if the year is a leap year
-
prolepticYear
public int prolepticYear(Era era, int yearOfEra)
Description copied from class:Chronology
Calculates the proleptic-year given the era and year-of-era.This combines the era and year-of-era into the single proleptic-year field.
- Specified by:
prolepticYear
in classChronology
- Parameters:
era
- the era of the correct type for the chronology, not nullyearOfEra
- the chronology year-of-era- Returns:
- the proleptic-year
-
eraOf
public ThaiBuddhistEra eraOf(int eraValue)
Description copied from class:Chronology
Creates the chronology era object from the numeric value.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.
- Specified by:
eraOf
in classChronology
- Parameters:
eraValue
- the era value- Returns:
- the calendar system era, not null
-
eras
public List<Era> eras()
Description copied from class:Chronology
Gets the list of eras for the 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.
- Specified by:
eras
in classChronology
- Returns:
- the list of eras for the chronology, may be immutable, not null
-
range
public ValueRange range(ChronoField field)
Description copied from class:Chronology
Gets the range of valid values for the specified field.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.
- Specified by:
range
in classChronology
- Parameters:
field
- the field to get the range for, not null- Returns:
- the range of valid values for the field, not null
-
resolveDate
public ThaiBuddhistDate resolveDate(Map<TemporalField,Long> fieldValues, ResolverStyle resolverStyle)
Description copied from class:Chronology
Resolves parsedChronoField
values into a date during parsing.Most
TemporalField
implementations are resolved using the resolve method on the field. By contrast, theChronoField
class defines fields that only have meaning relative to the chronology. As such,ChronoField
date fields are resolved here in the context of a specific chronology.The default implementation, which explains typical resolve behaviour, is provided in
AbstractChronology
.- Specified by:
resolveDate
in classChronology
- Parameters:
fieldValues
- the map of fields to values, which can be updated, not nullresolverStyle
- the requested type of resolve, not null- Returns:
- the resolved date, null if insufficient information to create a date
