The Minguo calendar system.
This chronology defines the rules of the Minguo calendar system. This calendar system is primarily used in the Republic of China, often known as Taiwan. Dates are aligned such that 0001-01-01 (Minguo) is 1912-01-01 (ISO).
The fields are defined as follows:
- era - There are two eras, the current 'Republic' (ERA_ROC) and the previous era (ERA_BEFORE_ROC).
- 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 minus 1911.
- 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 minus 1911.
- month-of-year - The Minguo month-of-year exactly matches ISO.
- day-of-month - The Minguo day-of-month exactly matches ISO.
- day-of-year - The Minguo day-of-year exactly matches ISO.
- leap-year - The Minguo leap-year pattern exactly matches ISO, such that the two calendars are never out of step.

public MinguoDate date(TemporalAccessor temporal)
```
    从接口复制的说明: Chronology
    
    Obtains a local date in this chronology from another temporal object.
    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 ChronoField#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.

    从接口复制的说明: Chronology
    
    Obtains a local date-time in this chronology from another temporal object.
    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.

public ChronoZonedDateTime<MinguoDate> zonedDateTime(TemporalAccessor temporal)
```
    从接口复制的说明: Chronology
    
    Obtains a 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 allowing it to be used as a query via method reference, aChronology::zonedDateTime.

public boolean isLeapYear(long prolepticYear)
```
    Checks if the specified year is a leap year.
    Minguo 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.
    
    指定者:
    
    isLeapYear 在接口中 Chronology
    
    参数:
    
    prolepticYear - the proleptic-year to check, not validated for range

```
    从接口复制的说明: 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.
    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.

    the proleptic-year
  - eraOf
```
public MinguoEra eraOf(int eraValue)
```
    从接口复制的说明: 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.
    
    指定者:
    
    eraOf 在接口中 Chronology
    
    参数:
    
    eraValue - the era value

    the calendar system era, not null
  - eras
```
public List<Era> eras()
```
    从接口复制的说明: 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.
    
    指定者:
    
    eras 在接口中 Chronology
    
    返回:
    
    the list of eras for the chronology, may be immutable, not null
  - range
```
public ValueRange range(ChronoField field)
```
    从接口复制的说明: 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.
    
    指定者:
    
    range 在接口中 Chronology
    
    参数:
    
    field - the field to get the range for, not null
    
    返回:

  - resolveDate
```
public MinguoDate resolveDate(Map<TemporalField,Long> fieldValues,
                              ResolverStyle resolverStyle)
```
    从类复制的说明: AbstractChronology
    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.
    ChronoField instances are resolved by this method, which may be overridden in subclasses.
    - EPOCH_DAY - If present, this is converted to a date and all other date fields are then cross-checked against the date.
    - PROLEPTIC_MONTH - If present, then it is split into the YEAR and MONTH_OF_YEAR. If the mode is strict or smart then the field is validated.
    - YEAR_OF_ERA and ERA - If both are present, then they are combined to form a YEAR. In lenient mode, the YEAR_OF_ERA range is not validated, in smart and strict mode it is. The ERA is validated for range in all three modes. If only the YEAR_OF_ERA is present, and the mode is smart or lenient, then the last available era is assumed. In strict mode, no era is assumed and the YEAR_OF_ERA is left untouched. If only the ERA is present, then it is left untouched.
    - YEAR, MONTH_OF_YEAR and DAY_OF_MONTH - If all three are present, then they are combined to form a date. In all three modes, the YEAR is validated. If the mode is smart or strict, then the month and day are validated. If the mode is lenient, then the date is combined in a manner equivalent to creating a date on the first day of the first month in the requested year, then adding the difference in months, then the difference in days. If the mode is smart, and the day-of-month is greater than the maximum for the year-month, then the day-of-month is adjusted to the last day-of-month. If the mode is strict, then the three fields must form a valid date.
    - YEAR and DAY_OF_YEAR - If both are present, then they are combined to form a date. In all three modes, the YEAR is validated. If the mode is lenient, then the date is combined in a manner equivalent to creating a date on the first day of the requested year, then adding the difference in days. If the mode is smart or strict, then the two fields must form a valid date.
    - YEAR, MONTH_OF_YEAR, ALIGNED_WEEK_OF_MONTH and ALIGNED_DAY_OF_WEEK_IN_MONTH - If all four are present, then they are combined to form a date. In all three modes, the YEAR is validated. If the mode is lenient, then the date is combined in a manner equivalent to creating a date on the first day of the first month in the requested year, then adding the difference in months, then the difference in weeks, then in days. If the mode is smart or strict, then the all four fields are validated to their outer ranges. The date is then combined in a manner equivalent to creating a date on the first day of the requested year and month, then adding the amount in weeks and days to reach their values. If the mode is strict, the date is additionally validated to check that the day and week adjustment did not change the month.
    - YEAR, MONTH_OF_YEAR, ALIGNED_WEEK_OF_MONTH and DAY_OF_WEEK - If all four are present, then they are combined to form a date. The approach is the same as described above for years, months and weeks in ALIGNED_DAY_OF_WEEK_IN_MONTH. The day-of-week is adjusted as the next or same matching day-of-week once the years, months and weeks have been handled.
    - YEAR, ALIGNED_WEEK_OF_YEAR and ALIGNED_DAY_OF_WEEK_IN_YEAR - If all three are present, then they are combined to form a date. In all three modes, the YEAR is validated. If the mode is lenient, then the date is combined in a manner equivalent to creating a date on the first day of the requested year, then adding the difference in weeks, then in days. If the mode is smart or strict, then the all three fields are validated to their outer ranges. The date is then combined in a manner equivalent to creating a date on the first day of the requested year, then adding the amount in weeks and days to reach their values. If the mode is strict, the date is additionally validated to check that the day and week adjustment did not change the year.
    - YEAR, ALIGNED_WEEK_OF_YEAR and DAY_OF_WEEK - If all three are present, then they are combined to form a date. The approach is the same as described above for years and weeks in ALIGNED_DAY_OF_WEEK_IN_YEAR. The day-of-week is adjusted as the next or same matching day-of-week once the years and weeks have been handled.
    The default implementation is suitable for most calendar systems. If ChronoField.YEAR_OF_ERA is found without an ChronoField.ERA then the last era in Chronology.eras() is used. The implementation assumes a 7 day week, that the first day-of-month has the value 1, that first day-of-year has the value 1, and that the first of the month and year always exists.
