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

value as defined above, create a newjava.util.GregorianCalendar(timeZone,Locale.getDefault())
. - Initialize all GregorianCalendar fields by calling
Calendar.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)

- Using
toGregorianCalendar
public java.util.GregorianCalendar toGregorianCalendar(java.util.TimeZone timezone, java.util.Locale aLocale, javax.xml.datatype.XMLGregorianCalendar defaults)
Convert thisXMLGregorianCalendar
along with provided parameters to aGregorianCalendar
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 ajava.util.TimeZone
with a custom timezone id using thethis.getTimezone()
. - else when
defaults.getTimezone() != FIELD_UNDEFINED
, create ajava.util.TimeZone
with a custom timezone id usingdefaults.getTimezone()
. - else use the
GregorianCalendar
default timezone value for the host is defined as specified byjava.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 theLocale
parameter. - Initialize all GregorianCalendar fields by calling
Calendar.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)
- Specified by:
toGregorianCalendar
in classjavax.xml.datatype.XMLGregorianCalendar
- Parameters:
timezone
- provide Timezone.null
is a legal value.aLocale
- provide explicit Locale. Use default GregorianCalendar locale if value isnull
.defaults
- provide default field values to use when corresponding field for this instance is FIELD_UNDEFINED or null. Ifdefaults
isnull
or a field within the specifieddefaults
is undefined, just usejava.util.GregorianCalendar
defaults.- Returns:
- a java.util.GregorianCalendar conversion of this instance.
- when parameter
getTimeZone
public java.util.TimeZone getTimeZone(int defaultZoneoffset)
Returns ajava.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).
- Specified by:
getTimeZone
in classjavax.xml.datatype.XMLGregorianCalendar
- Parameters:
defaultZoneoffset
- default zoneoffset if this zoneoffset isDatatypeConstants.FIELD_UNDEFINED
.- Returns:
- TimeZone for this.
