All Implemented Interfaces:

Serializable

public final class ISOChronology
extends AssembledChronology

Implements a chronology that follows the rules of the ISO8601 standard, which is compatible with Gregorian for all modern dates. When ISO does not define a field, but it can be determined (such as AM/PM) it is included.

With the exception of century related fields, ISOChronology is exactly the same as GregorianChronology. In this chronology, centuries and year of century are zero based. For all years, the century is determined by dropping the last two digits of the year, ignoring sign. The year of century is the value of the last two year digits.

ISOChronology is thread-safe and immutable.

Method Detail

getInstanceUTC

public static ISOChronology getInstanceUTC()

Gets an instance of the ISOChronology. The time zone of the returned instance is UTC.

Returns:

a singleton UTC instance of the chronology

getInstance

public static ISOChronology getInstance()

Gets an instance of the ISOChronology in the default time zone.

Returns:

a chronology in the default time zone

getInstance

public static ISOChronology getInstance(DateTimeZone zone)

Gets an instance of the ISOChronology in the given time zone.

Parameters:

zone - the time zone to get the chronology in, null is default

Returns:

a chronology in the specified time zone

withUTC

public Chronology withUTC()

toString in class BaseChronology

Returns:

a debugging string

assemble

protected void assemble(AssembledChronology.Fields fields)

Description copied from class: AssembledChronology

assemble in class AssembledChronology

Parameters:

fields - container of fields

equals

public boolean equals(Object obj)

Checks if this chronology instance equals another.

Overrides:

equals in class Object

Parameters:

obj - the object to compare to

Returns:

true if equal

Since:

1.6

hashCode

public int hashCode()

A suitable hash code for the chronology.

Overrides:

hashCode in class Object

Returns:

the hash code

Since:
