Method Detail

getChronology

public Chronology getChronology(java.lang.Object object,
                                Chronology chrono)

Gets the chronology.

If a chronology is specified then it is used. Otherwise, it is the GJChronology if a GregorianCalendar is used, BuddhistChronology if a BuddhistCalendar is used or ISOChronology otherwise. The time zone is extracted from the calendar if possible, default used if not.

Specified by:

getChronology in interface InstantConverter

Specified by:

getChronology in interface PartialConverter

Overrides:

getChronology in class AbstractConverter

Parameters:

object - the Calendar to convert, must not be null

chrono - the chronology to use, null means use Calendar

Returns:

the chronology, never null

Throws:

java.lang.NullPointerException - if the object is null

java.lang.ClassCastException - if the object is an invalid type

getChronology

public Chronology getChronology(java.lang.Object object,
                                DateTimeZone zone)

Gets the chronology, which is the GJChronology if a GregorianCalendar is used, BuddhistChronology if a BuddhistCalendar is used or ISOChronology otherwise. The time zone specified is used in preference to that on the calendar.

Specified by:

getChronology in interface InstantConverter

Specified by:

getChronology in interface PartialConverter

Overrides:

getChronology in class AbstractConverter

Parameters:

object - the Calendar to convert, must not be null

zone - the specified zone to use, null means default zone

Returns:

the chronology, never null

Throws:

java.lang.NullPointerException - if the object is null

java.lang.ClassCastException - if the object is an invalid type

getInstantMillis

public long getInstantMillis(java.lang.Object object,
                             Chronology chrono)

Gets the millis, which is the Calendar millis value.

Specified by:

getInstantMillis in interface InstantConverter

Overrides:

getInstantMillis in class AbstractConverter

Parameters:

object - the Calendar to convert, must not be null

chrono - the chronology result from getChronology, non-null

Returns:

the millisecond value

Throws:

java.lang.NullPointerException - if the object is null

java.lang.ClassCastException - if the object is an invalid type

getSupportedType

public java.lang.Class<?> getSupportedType()

Returns Calendar.class.

Specified by:

getSupportedType in interface Converter

Returns:

Calendar.class
