• toGregorianCalendar

  public 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(TimeZone, Locale, XMLGregorianCalendar).

  Field by Field Conversion from this class to java.util.GregorianCalendar
  java.util.GregorianCalendar field	javax.xml.datatype.XMLGregorianCalendar field
  ERA	getEonAndYear() .signum() < 0 ? GregorianCalendar.BC : GregorianCalendar.AD
  YEAR	getEonAndYear().abs().intValue()*
  MONTH	getMonth() - DatatypeConstants.JANUARY + Calendar.JANUARY
  DAY_OF_MONTH	getDay()
  HOUR_OF_DAY	getHour()
  MINUTE	getMinute()
  SECOND	getSecond()
  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 higher precision 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 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 class XMLGregorianCalendar

  See Also:

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

• toGregorianCalendar

  public 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 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().

  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 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 class XMLGregorianCalendar

  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 defaults is 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.

• 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).

  Specified by:

  getTimeZone in class XMLGregorianCalendar

  Parameters:

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

  Returns:

  TimeZone for this.

• toXMLFormat

  public String toXMLFormat(QName datatype) throws IllegalArgumentException, IllegalStateException

  Formats the string in XML for the datatype if possible.

  Parameters:

  datatype - The XML date/time datatype.

  Throws:

  IllegalArgumentException - If the datatype

  IllegalStateException - If the combination of set fields does not match one of the eight defined XML Schema built-in date/time datatypes.
