Method Details

of

public static CyclicYear of(int yearOfCycle)

Obtains an instance of cyclic year.

Parameters:

yearOfCycle - year number in the range 1-60

Returns:

CyclicYear

Throws:

IllegalArgumentException - if the parameter is out of range

of

public static CyclicYear of(SexagesimalName.Stem stem,
 SexagesimalName.Branch branch)

Obtains an instance of cyclic year.

Parameters:

stem - celestial stem

branch - terrestrial branch

Returns:

CyclicYear

Throws:

IllegalArgumentException - if the combination of stem and branch is invalid

parse

public static CyclicYear parse(String text,
 Locale locale)
                        throws ParseException

Parses the given localized name as a combination of stem and branch to a cyclic year.

The original Chinese names are usually not translatable. A few languages like Korean, Vietnamese and Russian use their own transcriptions. The pinyin-transcription (official Chinese romanization) serves as fallback for other languages. And the root locale will use a simplified version of pinyin without diacritic accents. This method will always expect a minus sign as separator between stem and branch unless the language is Chinese, Korean or Japanese.

Parameters:

text - the text to be parsed

locale - language

Returns:

parsed cyclic year

Throws:

ParseException - if the text cannot be parsed

SexagesimalName.getDisplayName(Locale)

roll

public CyclicYear roll(int amount)

Rolls this cyclic year by given amount.

Overrides:

roll in class SexagesimalName

Parameters:

amount - determines how many years/units this instance should be rolled

Returns:

changed copy of this instance

inQingDynasty

public EastAsianYear inQingDynasty(ChineseEra era)

Obtains an unambivalent year reference for given Qing dynasty.

Note: The years AD 1662 and AD 1722 have the same cyclic year so an unambivalent year reference cannot be determined. This is because the Kangxi-era was 61 years long.

Parameters:

era - the Chinese era representing a historic Qing dynasty

Returns:

EastAsianYear

Throws:

IllegalArgumentException - if the era is not a Qing dynasty or if the combination of this cyclic year together with the era is ambivalent (rare case in QING_KANGXI_1662_1723)

inCycle

public EastAsianYear inCycle(int cycle)

Obtains a year reference for given cycle number (technical identifier).

Parameters:

cycle - number of sexagesimal year cycle

Returns:

EastAsianYear

Throws:

IllegalArgumentException - if the cycle is smaller than 1
