XMLGregorianCalendarImplpublic class XMLGregorianCalendarImpl extends XMLGregorianCalendar implements Serializable, CloneableRepresentation for W3C XML Schema 1.0 date/time datatypes.
Specifically, these date/time datatypes are
{@link DatatypeConstants#DATETIME dateTime},
{@link DatatypeConstants#TIME time},
{@link DatatypeConstants#DATE date},
{@link DatatypeConstants#GYEARMONTH gYearMonth},
{@link DatatypeConstants#GMONTHDAY gMonthDay},
{@link DatatypeConstants#GYEAR gYear},
{@link DatatypeConstants#GMONTH gMonth} and
{@link DatatypeConstants#GDAY gDay}
defined in the XML Namespace
"http://www.w3.org/2001/XMLSchema".
These datatypes are normatively defined in
W3C XML Schema 1.0 Part 2, Section 3.2.7-14.
The table below defines the mapping between XML Schema 1.0
date/time datatype fields and this class' fields. It also summarizes
the value constraints for the date and time fields defined in
W3C XML Schema 1.0 Part 2, Appendix D,
ISO 8601 Date and Time Formats.

XMLGregorianCalendar
Accessor(s) |
Value Range |
| year |
{@link #getYear()} + {@link #getEon()} or
{@link #getEonAndYear}
|
getYear() is a value between -(10^9-1) to (10^9)-1
or {@link DatatypeConstants#FIELD_UNDEFINED}.
{@link #getEon()} is high order year value in billion of years.
getEon() has values greater than or equal to (10^9) or less than or equal to -(10^9).
A value of null indicates field is undefined.
Given that XML Schema 1.0 errata states that the year zero
will be a valid lexical value in a future version of XML Schema,
this class allows the year field to be set to zero. Otherwise,
the year field value is handled exactly as described
in the errata and [ISO-8601-1988]. Note that W3C XML Schema 1.0
validation does not allow for the year field to have a value of zero.
|
| month |
{@link #getMonth()} |
1 to 12 or {@link DatatypeConstants#FIELD_UNDEFINED} |
| day |
{@link #getDay()} |
Independent of month, max range is 1 to 31 or {@link DatatypeConstants#FIELD_UNDEFINED}.
The normative value constraint stated relative to month
field's value is in W3C XML Schema 1.0 Part 2, Appendix D.
|
| hour |
{@link #getHour()} |
0 to 24 or {@link DatatypeConstants#FIELD_UNDEFINED}
For a value of 24, the minute and second field must be zero.
|
| minute |
{@link #getMinute()} |
0 to 59 or {@link DatatypeConstants#FIELD_UNDEFINED} |
| second |
{@link #getSecond()} + {@link #getMillisecond()}/1000 or
{@link #getSecond()} + {@link #getFractionalSecond()}
|
{@link #getSecond()} from 0 to 60 or {@link DatatypeConstants#FIELD_UNDEFINED}.
(Note: 60 only allowable for leap second.)
{@link #getFractionalSecond()} allows for infinite precision over the range from 0.0 to 1.0 when
the {@link #getSecond()} is defined.
FractionalSecond is optional and has a value of null when it is undefined.
{@link #getMillisecond()} is the convenience
millisecond precision of value of {@link #getFractionalSecond()}.
|
| timezone |
{@link #getTimezone()} |
Number of minutes or {@link DatatypeConstants#FIELD_UNDEFINED}.
Value range from -14 hours (-14 * 60 minutes) to 14 hours (14 * 60 minutes).
|
All maximum value space constraints listed for the fields in the table
above are checked by factory methods, setter methods and parse methods of
this class. IllegalArgumentException is thrown when
parameter's value is outside the maximum value constraint for the field.
Validation checks, for example, whether days in month should be
limited to 29, 30 or 31 days, that are dependent on the values of other
fields are not checked by these methods.
The following operations are defined for this class:
- factory methods to create instances
- accessors/mutators for independent date/time fields
- conversion between this class and W3C XML Schema 1.0 lexical representation
- conversion between this class and
java.util.GregorianCalendar
- partial order relation comparator method, {@link #compare(XMLGregorianCalendar)}
- {@link #equals(Object)} defined relative to {@link #compare(XMLGregorianCalendar)}.
- addition operation with {@link javax.xml.datatype.Duration}.

| | public java.util.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
{@link #toGregorianCalendar(TimeZone, Locale, XMLGregorianCalendar)}.

manner.

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

- when parameter
timeZone is non-null,
it is the timezone field.

create a java.util.TimeZone with a custom timezone id
using the this.getTimezone().
