public class XSDDateTime

extends AbstractDateTime

Represent an XSD date/time value. Rather than have a separate type for each legal date/time value combination this is a combination type than does runtime checks whether a given field is legal in the current circumstances.

Constructor Summary

XSDDateTime(java.util.Calendar date)           Constructor - create a full DateTime object from a java calendar instance.

XSDDateTime(java.lang.Object value, int mask)           Constructor - should only be used by the internals but public scope because the internals spread across multiple packages.

 

Method Summary
java.util.Calendar	asCalendar()           Return the date time as a java Calendar object.
private static int[]	convertCalendar(java.util.Calendar date)           Convert a java calendar object to a new int[] in the format used by XSDAbstractDateTime
int	getDays()           Return the number of years in the dateTime
int	getFullSeconds()           Return the number of full seconds in the dateTime
int	getHours()           Return the number of hours in the dateTime
int	getMinutes()           Return the number of minutes in the dateTime
int	getMonths()           Return the month in the dateTime, this is in ISO8601 format so january = 1
double	getSeconds()           Return the number of seconds in the dateTime, including fractional part
double	getTimePart()           Return the time component of the dateTime - i.e.
int	getYears()           Return the number of years in the dateTime.
java.lang.String	toString()           Return legal serialized form.

See Also:

Constant Field Values

---

maskMap

public static final java.util.HashMap maskMap

table mapping xs type name to mask of legal values

---

mask

protected short mask

Set of legal fields for the particular date/time instance

Constructor Detail

XSDDateTime

public XSDDateTime(java.lang.Object value,
                   int mask)

Constructor - should only be used by the internals but public scope because the internals spread across multiple packages.

---

XSDDateTime

public XSDDateTime(java.util.Calendar date)

Constructor - create a full DateTime object from a java calendar instance.

Method Detail

convertCalendar

private static int[] convertCalendar(java.util.Calendar date)

Convert a java calendar object to a new int[] in the format used by XSDAbstractDateTime

---

asCalendar

public java.util.Calendar asCalendar()
                              throws IllegalDateTimeFieldException

Return the date time as a java Calendar object. If the timezone has been specified then the object is normalized to GMT. If the zone has not been specified then we use the default timezone.

N.B. The millisecond field will be discarded and the resulting Calendar object will have 0 in the millisecond field. This is a workaround for an apparent problem with some Linux JDK's Calendar implementations. If it causes a problem contact us to ask us to revisit this.

---

getYears

public int getYears()
             throws IllegalDateTimeFieldException

Return the number of years in the dateTime.

---

getMonths

public int getMonths()
              throws IllegalDateTimeFieldException

Return the month in the dateTime, this is in ISO8601 format so january = 1

---

getDays

public int getDays()
            throws IllegalDateTimeFieldException

Return the number of years in the dateTime

             throws IllegalDateTimeFieldException

Return the number of hours in the dateTime

---

getMinutes

public int getMinutes()
               throws IllegalDateTimeFieldException

Return the number of minutes in the dateTime

---

getFullSeconds

public int getFullSeconds()
                   throws IllegalDateTimeFieldException

Return the number of full seconds in the dateTime

---

getSeconds

public double getSeconds()
                  throws IllegalDateTimeFieldException

Return the number of seconds in the dateTime, including fractional part

---

getTimePart

public double getTimePart()
                   throws IllegalDateTimeFieldException

Return the time component of the dateTime - i.e. just the hours/mins/seconds, and returns the values in seconds.

---

toString

public java.lang.String toString()

Return legal serialized form.
