duration - DurationImpl to add to this XMLGregorianCalendarImpl.

Throws:

NullPointerException - when duration parameter is null.

toGregorianCalendar

public GregorianCalendar toGregorianCalendar()

Convert this to java.util.GregorianCalendar.

When this instance has an undefined field, this conversion relies on the java.util.GregorianCalendar default for its corresponding field. A notable difference between XML Schema 1.0 date/time datatypes and java.util.GregorianCalendar is that Timezone value is optional for date/time datatypes and it is a required field for java.util.GregorianCalendar. See javadoc for java.util.TimeZone.getDefault() on how the default is determined. To explicitly specify the TimeZone instance, see toGregorianCalendar(TimeZone, Locale, XMLGregorianCalendarImpl).

Field by Field Conversion from this class to java.util.GregorianCalendar
java.util.GregorianCalendar field	javax.xml.datatype.XMLGregorianCalendarImpl field
ERA	getEonAndYear().signum() invalid input: '<' 0 ? GregorianCalendar.BC : GregorianCalendar.AD
YEAR	getEonAndYear().abs().intValue()*
MONTH	getMonth() - 1
DAY_OF_MONTH	getDay()
AM_PM	getHour() invalid input: '<' 12 : Calendar.AM : Calendar.PM
HOUR_OF_DAY	getHour()
MINUTE	getMinute()

MILLISECOND	get millisecond order from getFractionalSecond()*
GregorianCalendar.setTimeZone(TimeZone)	getTimezone() formatted into Custom timezone id

* designates possible loss of precision during the conversion due to source datatype having higer precison than target datatype.

To ensure consistency in conversion implementations, the new GregorianCalendar should be instantiated in following manner.

• Using timeZone value as defined above, create a new java.util.GregorianCalendar(timeZone,Locale.getDefault()).
• Initialize all GregorianCalendar fields by calling {(@link GegorianCalendar#clear()}.
• Obtain a pure Gregorian Calendar by invoking GregorianCalendar.setGregorianChange( new Date(Long.MIN_VALUE)).
• Its fields ERA, YEAR, MONTH, DAY_OF_MONTH, HOUR_OF_DAY, MINUTE, SECOND and MILLISECOND are set using the method Calendar.set(int,int)

See Also:

• toGregorianCalendar(java.util.TimeZone, java.util.Locale, XMLGregorianCalendarImpl)

toGregorianCalendar

public GregorianCalendar toGregorianCalendar(TimeZone timezone,
 Locale aLocale,
 XMLGregorianCalendarImpl defaults)

Convert this along with provided parameters to java.util.GregorianCalendar instance.

Since XML Schema 1.0 date/time datetypes has no concept of timezone ids or daylight savings timezone ids, this conversion operation allows the user to explicitly specify one with timezone parameter.

To compute the return value's TimeZone field,

• when parameter timeZone is non-null, it is the timezone field.
• else when this.getTimezone() != FIELD_UNDEFINED, create a java.util.TimeZone with a custom timezone id using the this.getTimezone().
• else when defaults.getTimezone() != FIELD_UNDEFINED, create a java.util.TimeZone with a custom timezone id using defaults.getTimezone().
• else use the GregorianCalendar default timezone value for the host is definedas specified by java.util.TimeZone.getDefault().

To ensure consistency in conversion implementations, the new GregorianCalendar should be instantiated in following manner.

• Create a new java.util.GregorianCalendar(TimeZone, Locale) with TimeZone set as specified above and the Locale parameter.
• Initialize all GregorianCalendar fields by calling {(@link GegorianCalendar#clear()}.
• Obtain a pure Gregorian Calendar by invoking GregorianCalendar.setGregorianChange( new Date(Long.MIN_VALUE)).
• Its fields ERA, YEAR, MONTH, DAY_OF_MONTH, HOUR_OF_DAY, MINUTE, SECOND and MILLISECOND are set using the method Calendar.set(int,int)

Parameters:

timezone - provide Timezone. null is a legal value.

aLocale - provide explicit Locale. Use default GregorianCalendar locale if value is null.

defaults - provide default field values to use when corresponding field for this instance is FIELD_UNDEFINED or null. If defaultsis null or a field within the specified defaults is undefined, just use java.util.GregorianCalendar defaults.

Returns:

a java.util.GregorianCalendar conversion of this instance.

See Also:

• LEAP_YEAR_DEFAULT

getTimeZone

public TimeZone getTimeZone(int defaultZoneoffset)

Returns a java.util.TimeZone for this class.

If timezone field is defined for this instance, returns TimeZone initialized with custom timezone id of zoneoffset. If timezone field is undefined, try the defaultZoneoffset that was passed in. If defaultZoneoffset is FIELD_UNDEFINED, return default timezone for this host. (Same default as java.util.GregorianCalendar).

Parameters:

defaultZoneoffset - default zoneoffset if this zoneoffset is DatatypeConstants.FIELD_UNDEFINED.

Returns:

TimeZone for this.
