Method Details

assemble

protected void assemble(AssembledChronology.Fields fields)
Overrides:
assemble in interface AssembledChronology

equals

public boolean equals(Object obj)
A zoned chronology is only equal to a zoned chronology with the same base chronology and zone.
Parameters:
obj - the object to compare to
Returns:
true if equal
Since:
1.4

getDateTimeMillis

public long getDateTimeMillis(int year,
                              int monthOfYear,
                              int dayOfMonth,
                              int millisOfDay)
            throws IllegalArgumentException
Returns a datetime millisecond instant, formed from the given year, month, day, and millisecond values. The set of given values must refer to a valid datetime, or else an IllegalArgumentException is thrown.

The default implementation calls upon separate DateTimeFields to determine the result. Subclasses are encouraged to provide a more efficient implementation.

Overrides:
getDateTimeMillis in interface AssembledChronology
Parameters:
year - year to use
monthOfYear - month to use
dayOfMonth - day of month to use
millisOfDay - millisecond to use
Returns:
millisecond instant from 1970-01-01T00:00:00Z

getDateTimeMillis

public long getDateTimeMillis(int year,
                              int monthOfYear,
                              int dayOfMonth,
                              int hourOfDay,
                              int minuteOfHour,
                              int secondOfMinute,
                              int millisOfSecond)
            throws IllegalArgumentException
Returns a datetime millisecond instant, formed from the given year, month, day, hour, minute, second, and millisecond values. The set of given values must refer to a valid datetime, or else an IllegalArgumentException is thrown.

The default implementation calls upon separate DateTimeFields to determine the result. Subclasses are encouraged to provide a more efficient implementation.

Overrides:
getDateTimeMillis in interface AssembledChronology
Parameters:
year - year to use
monthOfYear - month to use
dayOfMonth - day of month to use
hourOfDay - hour to use
minuteOfHour - minute to use
secondOfMinute - second to use
millisOfSecond - millisecond to use
Returns:
millisecond instant from 1970-01-01T00:00:00Z

getDateTimeMillis

public long getDateTimeMillis(long instant,
                              int hourOfDay,
                              int minuteOfHour,
                              int secondOfMinute,
                              int millisOfSecond)
            throws IllegalArgumentException
Returns a datetime millisecond instant, from from the given instant, hour, minute, second, and millisecond values. The set of given values must refer to a valid datetime, or else an IllegalArgumentException is thrown.

The default implementation calls upon separate DateTimeFields to determine the result. Subclasses are encouraged to provide a more efficient implementation.

Overrides:
getDateTimeMillis in interface AssembledChronology
Parameters:
instant - instant to start from
hourOfDay - hour to use
minuteOfHour - minute to use
secondOfMinute - second to use
millisOfSecond - millisecond to use
Returns:
millisecond instant from 1970-01-01T00:00:00Z

getInstance

public static ZonedChronology getInstance(Chronology base,
                                          DateTimeZone zone)
Create a ZonedChronology for any chronology, overriding any time zone it may already have.
Parameters:
base - base chronology to wrap
zone - the time zone

getZone

public DateTimeZone getZone()
Returns the DateTimeZone that this Chronology operates in, or null if unspecified.
Overrides:
getZone in interface AssembledChronology
Returns:
DateTimeZone null if unspecified

hashCode

public int hashCode()
A suitable hashcode for the chronology.
Returns:
the hashcode
Since:
1.4

toString

public String toString()
A debugging string for the chronology.
Overrides:
toString in interface BaseChronology
Returns:
the debugging string

withUTC

public Chronology withUTC()
Returns an instance of this Chronology that operates in the UTC time zone. Chronologies that do not operate in a time zone or are already UTC must return themself.
Overrides:
withUTC in interface BaseChronology
Returns:
a version of this chronology that ignores time zones

withZone

public Chronology withZone(DateTimeZone zone)
Returns an instance of this Chronology that operates in any time zone.
Overrides:
withZone in interface BaseChronology
Parameters:
zone - to use, or default if null
Returns:
a version of this chronology with a specific time zone
