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) is 1941-01-01 (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.

```
    Description copied from class: Chronology
    
    Obtains a local date in this chronology from another temporal object.
    This creates a date in this chronology based on the specified TemporalAccessor.
    The standard mechanism for conversion between date types is the local epoch-day field.
    
    Specified by:
    
    date in class Chronology
    
    Parameters:
    temporal - the temporal object to convert, not null

```
public ChronoLocalDateTime<ThaiBuddhistDate> localDateTime(TemporalAccessor temporal)
```
    Description copied from class: Chronology
    
    Obtains a local date-time in this chronology from another temporal object.
    This creates a date-time in this chronology based on the specified TemporalAccessor.
    The date of the date-time should be equivalent to that obtained by calling Chronology.date(TemporalAccessor). The standard mechanism for conversion between time types is the nano-of-day field.
    
    Overrides:
    
    localDateTime in class Chronology
    
    Parameters:
    temporal - the temporal object to convert, not null

```
    Description copied from class: Chronology
    
    Obtains a zoned date-time in this chronology from another temporal object.
    This creates a date-time in this chronology based on the specified TemporalAccessor.
    This should obtain a ZoneId using ZoneId.from(TemporalAccessor). The date-time should be obtained by obtaining an Instant. If that fails, the local date-time should be used.
    
    Overrides:
    
    zonedDateTime in class Chronology
    
    Parameters:
    temporal - the temporal object to convert, not null
    
    Returns:
    the zoned date-time in this chronology, not null
  - zonedDateTime
```

                                                  ZoneId zone)
```
    Description copied from class: Chronology
    
    Obtains a zoned date-time in this chronology from an Instant.
    This creates a zoned date-time with the same instant as that specified.
    
    Overrides:
    
    zonedDateTime in class Chronology
    
    Parameters:
    instant - the instant to create the date-time from, not null
    zone - the time-zone, not null
    
    Returns:
    the zoned date-time, not null
  - 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 class Chronology
    
    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 class Chronology
    
    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 class Chronology
    
    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 class Chronology
    
    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 class Chronology
    
    Parameters:
    era - the era of the correct type for the chronology, not null
    yearOfEra - 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 class Chronology
    
    Parameters:
    eraValue - the era value
    
    Returns:
    the calendar system era, not null
  - eras
```
public java.util.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 class Chronology
    
    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 class Chronology
    
    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(java.util.Map<TemporalField,java.lang.Long> fieldValues,
                           ResolverStyle resolverStyle)
```
    Description copied from class: Chronology
    
    Resolves parsed ChronoField values into a date during parsing.
    Most TemporalField implementations are resolved using the resolve method on the field. By contrast, the ChronoField 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.
    
    Overrides:
    
    resolveDate in class Chronology
    
    Parameters:
    fieldValues - the map of fields to values, which can be updated, not null
    resolverStyle - the requested type of resolve, not null
    
    Returns:
    the resolved date, null if insufficient information to create a date
