Enum Constant Detail

OFFICIAL

public static final Nengo.Selector OFFICIAL

Selects all nengos with the exception of those of the northern court in the Nanboku-chō period (1336-1392).

This selector is the default.

MODERN

public static final Nengo.Selector MODERN

Selects only nengos from Meiji onwards (introduction of japanese-gregorian calendar in year 1873 = Meiji 6).

EDO_PERIOD

public static final Nengo.Selector EDO_PERIOD

Selects all nengos of the Edo period (1603-1868).

See also Wikipedia.

AZUCHI_MOMOYAMA_PERIOD

public static final Nengo.Selector AZUCHI_MOMOYAMA_PERIOD

Selects all nengos of the Azuchi-Momoyama period (1573-1603).

See also Wikipedia.

MUROMACHI_PERIOD

public static final Nengo.Selector MUROMACHI_PERIOD

Selects all nengos of the Muromachi period (1336-1573).

See also Wikipedia. The nengos of the Kenmu-restoration do not belong to this period. Furthermore, all nengos of the northern court are excluded because otherwise a historical order of generated lists is hard to achieve.

NORTHERN_COURT

public static final Nengo.Selector NORTHERN_COURT

Selects the nengos of the northern court only (during the Nanboku-chō period 1336-1392 and in addition, the nengo Shōkei (1332)).

The northern variant of the Nengo Kenmu (Kenmu restoration) is also matched by this selector.

SOUTHERN_COURT

public static final Nengo.Selector SOUTHERN_COURT

Selects the nengos of the southern court only (during the Nanboku-chō period 1336-1392).

The southern variant of the Nengo Kenmu (Kenmu restoration) is also matched by this selector. Historical note: The last year 10 of nengo Genchū was then replaced by Meitoku 4.

KAMAKURA_PERIOD

public static final Nengo.Selector KAMAKURA_PERIOD

Selects all nengos of the Kamakura period (1185-1332).

See also Wikipedia

HEIAN_PERIOD

public static final Nengo.Selector HEIAN_PERIOD

Selects all nengos of the Heian period (794-1185).

See also Wikipedia

NARA_PERIOD

public static final Nengo.Selector NARA_PERIOD

Selects all nengos of the Nara period (710-794).

See also Wikipedia

ASUKA_PERIOD

public static final Nengo.Selector ASUKA_PERIOD

Selects all nengos of the Asuka period (538-710).

See also Wikipedia. Time4J only supports the last three nengos of this period because the historical data are not exactly known and there were also historical gaps in nengo counting.

Method Detail

values

public static Nengo.Selector[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (Nengo.Selector c : Nengo.Selector.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static Nengo.Selector valueOf(String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

IllegalArgumentException - if this enum type has no constant with the specified name

NullPointerException - if the argument is null
