abstract
class
XMLGregorianCalendar
extends Object
implements
Cloneable
java.lang.Object | |
↳ | javax.xml.datatype.XMLGregorianCalendar |
Representation for W3C XML Schema 1.0 date/time datatypes.
Specifically, these date/time datatypes are
dateTime
,
time
,
date
,
gYearMonth
,
gMonthDay
,
gYear
gMonth
and
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.
Date/Time Datatype Field Mapping Between XML Schema 1.0 and Java Representation | ||
---|---|---|
XML Schema 1.0 datatype field |
Related XMLGregorianCalendar Accessor(s) |
Value Range |
year | getYear() + getEon() orgetEonAndYear()
|
getYear() is a value between -(10^9-1) to (10^9)-1
or DatatypeConstants.FIELD_UNDEFINED .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 | getMonth() |
1 to 12 or DatatypeConstants.FIELD_UNDEFINED |
day | getDay() |
Independent of month, max range is 1 to 31 or 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 | getHour() |
0 to 24 or DatatypeConstants.FIELD_UNDEFINED .
For a value of 24, the minute and second field must be zero per
XML Schema Errata.
|
minute | getMinute() |
0 to 59 or DatatypeConstants.FIELD_UNDEFINED |
second |
getSecond() + getMillisecond() /1000 orgetSecond() + getFractionalSecond()
|
getSecond() from 0 to 60 or DatatypeConstants.FIELD_UNDEFINED .(Note: 60 only allowable for leap second.) getFractionalSecond() allows for infinite precision over the range from 0.0 to 1.0 when
the getSecond() is defined.FractionalSecond is optional and has a value of null when it is undefined.getMillisecond() is the convenience
millisecond precision of value of getFractionalSecond() .
|
timezone | getTimezone() |
Number of minutes or 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, @{link DatatypeFactory},
setter methods and parse methods of
this class. IllegalArgumentException
is thrown when a
parameter's value is outside the value constraint for the field or
if the composite
values constitute an invalid XMLGregorianCalendar instance (for example, if
the 31st of June is specified).
The following operations are defined for this class:
- accessors/mutators for independent date/time fields
- conversion between this class and W3C XML Schema 1.0 lexical representation,
toString()
,DatatypeFactory.newXMLGregorianCalendar(String lexicalRepresentation)
- conversion between this class and
GregorianCalendar
,toGregorianCalendar(java.util.TimeZone, java.util.Locale, javax.xml.datatype.XMLGregorianCalendar)
,DatatypeFactory
- partial order relation comparator method,
compare(javax.xml.datatype.XMLGregorianCalendar)
equals(java.lang.Object)
defined relative tocompare(javax.xml.datatype.XMLGregorianCalendar)
.- addition operation with
Duration
instance as defined in W3C XML Schema 1.0 Part 2, Appendix E, Adding durations to dateTimes.

toGregorianCalendar
public abstract GregorianCalendar toGregorianCalendar ()
Convert this XMLGregorianCalendar
to a 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(java.util.TimeZone, Locale, javax.xml.datatype.XMLGregorianCalendar)
.

should be instantiated in following
manner.
- Using
timeZone
value as defined above, create a newjava.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)
Returns | |
---|---|
GregorianCalendar |
toGregorianCalendar
public abstract GregorianCalendar toGregorianCalendar (TimeZone timezone, Locale aLocale, XMLGregorianCalendar defaults)
Convert this XMLGregorianCalendar
along with provided parameters
to a 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 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
GregorianCalendar.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 |
TimeZone : provide Timezone. null is a legal value. |
aLocale |
Locale : provide explicit Locale. Use default GregorianCalendar locale if
value is null . |
defaults |
XMLGregorianCalendar : provide default field values to use when corresponding
field for this instance is FIELD_UNDEFINED or null.
If defaults is null or a field
within the specified defaults is undefined,
just use java.util.GregorianCalendar defaults. |
Returns | |
---|---|
GregorianCalendar |
a java.util.GregorianCalendar conversion of this instance. |
toString
public String toString ()
Returns a String
representation of this XMLGregorianCalendar
Object
.
The result is a lexical representation generated by toXMLFormat()
