Method Details

values

public static VietnameseCalendar.Unit[] values()

Returns an array containing the constants of this enum class, in the order they are declared.

Returns:

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

valueOf

public static VietnameseCalendar.Unit valueOf(String name)

Returns the enum constant of this class with the specified name. The string must match exactly an identifier used to declare an enum constant in this class. (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 class has no constant with the specified name

NullPointerException - if the argument is null

getLength

public double getLength()

Description copied from interface: ChronoUnit

Defines the typical length of this time unit in seconds without taking into account anomalies like timezone effects or leap seconds.

Important note: This method can only yield an estimated value and is not intended to assist in calculations of durations, but only in sorting of units.

Specified by:

getLength in interface ChronoUnit

Returns:

estimated decimal value in seconds

isCalendrical

public boolean isCalendrical()

Description copied from interface: ChronoUnit

Queries if this time unit is calendrical respective is at least as long as a calendar day.

Implementation note: The method must be consistent with the typical length of the unit. The expression Double.compare(unit.getLength(), 86400.0) >= 0 is equivalent to unit.isCalendrical().

Specified by:

isCalendrical in interface ChronoUnit

Returns:

true if at least as long as a day else false

between

public int between(VietnameseCalendar start,
 VietnameseCalendar end)

Calculates the difference between given Vietnamese dates in this unit.

Parameters:

start - start date (inclusive)

end - end date (exclusive)

Returns:

difference counted in this unit
