This optional field can only have a defined value when the xs:dateTime second field, represented by getSecond() , does not return DatatypeConstants.FIELD_UNDEFINED .

compare

Compare two instances of W3C XML Schema 1.0 date/time datatypes according to partial order relation defined in W3C XML Schema 1.0 Part 2, Section 3.2.7.3, Order relation on dateTime. xsd:dateTime datatype field mapping to accessors of this class are defined in date/time field mapping table.

normalize

Normalize this instance to UTC. 2000-03-04T23:00:00+03:00 normalizes to 2000-03-04T20:00:00Z Implements W3C XML Schema Part 2, Section 3.2.7.3 (A).

equals

Compares this calendar to the specified object. The result is true if and only if the argument is not null and is an XMLGregorianCalendar object that represents the same instant in time as this object.

hashCode

toXMLFormat

Return the lexical representation of this instance. The format is specified in XML Schema 1.0 Part 2, Section 3.2.12.1, Lexical Representation«. Specific target lexical representation format is determined by getXMLSchemaType() .

getXMLSchemaType

Return the name of the XML Schema date/time type that this instance maps to. Type is computed based on fields that are set.

Required fields for XML Schema 1.0 Date/Time Datatypes. (timezone is optional for all date/time datatypes)
Datatype	year	month	day	hour	minute	second
DatatypeConstants.DATETIME	X	X	X	X	X	X
DatatypeConstants.DATE	X	X	X
DatatypeConstants.TIME	X	X	X
DatatypeConstants.GYEARMONTH	X	X
DatatypeConstants.GMONTHDAY	X	X
DatatypeConstants.GYEAR	X
DatatypeConstants.GMONTH	X
DatatypeConstants.GDAY	X

toString

Returns a String representation of this XMLGregorianCalendar Object . The result is a lexical representation generated by toXMLFormat() .

isValid

public abstract boolean isValid()

add

Add duration to this instance. The computation is specified in XML Schema 1.0 Part 2, Appendix E, Adding durations to dateTimes>. date/time field mapping table defines the mapping from XML Schema 1.0 dateTime fields to this class’ representation of those fields.

toGregorianCalendar

Using timeZone value as defined above, create a new java.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)

toGregorianCalendar

public abstract GregorianCalendar toGregorianCalendar(TimeZone timezone, Locale aLocale, XMLGregorianCalendar defaults)

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 defined as specified by java.util.TimeZone.getDefault() .

Create a new java.util.GregorianCalendar(TimeZone, Locale) with TimeZone set as specified above and the Locale 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)

getTimeZone

public abstract 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).

If you had worked on a project which consume or publish web services, then you would have faced a problem with date (XMLGregorianCalendar) object, where you would like to send only date string as yyyy-MM-dd but complete yyyy-MM-dd’T’HH:mm:ss’Z’ has been sent. This date string contains date, time and timezone information, if you like to send only date string as yyyy-MM-dd then you have to remove time and timezone information from date object. Let’s see how to remove these information :-

To remove time zone or “Z” from date string, call following method :-

xmlDate.setTimezone( DatatypeConstants.FIELD_UNDEFINED )

To remove time information from date string, call following method :-

xmlDate.setTimezone( DatatypeConstants.FIELD_UNDEFINED, DatatypeConstants.FIELD_UNDEFINED, DatatypeConstants.FIELD_UNDEFINED, DatatypeConstants.FIELD_UNDEFINED )

Example :-

import java.util.Date; import java.util.GregorianCalendar; import javax.xml.datatype.DatatypeConstants; import javax.xml.datatype.DatatypeFactory; import javax.xml.datatype.XMLGregorianCalendar; public class Main < public static void main(String[] args) < XMLGregorianCalendar xmlDate = null; GregorianCalendar gc = new GregorianCalendar(); gc.setTime(new Date()); try < xmlDate = DatatypeFactory.newInstance().newXMLGregorianCalendar(gc); System.out.println("Complete Date :- " + xmlDate.toString()); // To remove Timezone or "Z" xmlDate.setTimezone(DatatypeConstants.FIELD_UNDEFINED); System.out.println("Without Time Zone :- " + xmlDate.toString()); // To remove Time information xmlDate.setTime(DatatypeConstants.FIELD_UNDEFINED, DatatypeConstants.FIELD_UNDEFINED, DatatypeConstants.FIELD_UNDEFINED, DatatypeConstants.FIELD_UNDEFINED); System.out.println("Without Time Zone &amp; Time :- " + xmlDate.toString()); >catch (Exception e) < e.printStackTrace(); >> >

Result :-

That’s all for this post, If you liked it, please share your thoughts in comments section and share it with others too.
