Constructor Detail

GMonthDayValue

public GMonthDayValue(CharSequence value)
               throws XPathException

Throws:

XPathException

GMonthDayValue

public GMonthDayValue(byte month,
                      byte day,
                      int tz)

GMonthDayValue

public GMonthDayValue(byte month,
                      byte day,
                      int tz,
                      AtomicType type)

Method Detail

copy

public AtomicValue copy(AtomicType typeLabel)

Make a copy of this date, time, or dateTime value

Specified by:

copy in class AtomicValue

Parameters:

typeLabel -

getPrimitiveType

public BuiltInAtomicType getPrimitiveType()

Determine the primitive type of the value. This delivers the same answer as getItemType().getPrimitiveItemType(). The primitive types are the 19 primitive types of XML Schema, plus xs:integer, xs:dayTimeDuration and xs:yearMonthDuration, and xs:untypedAtomic. For external objects, the result is AnyAtomicType.

Specified by:

getPrimitiveType in class AtomicValue

convertPrimitive

public AtomicValue convertPrimitive(BuiltInAtomicType requiredType,
                                    boolean validate,
                                    XPathContext context)

Convert to target data type

Specified by:

convertPrimitive in class AtomicValue

Parameters:

requiredType - an integer identifying the required atomic type

context -

validate - true if validation is required. If set to false, the caller guarantees that the value is valid for the target data type, and that further validation is therefore not required. Note that a validation failure may be reported even if validation was not requested.

Returns:

an AtomicValue, a value of the required type; or an ErrorValue

getStringValueCS

public CharSequence getStringValueCS()

Description copied from class: AtomicValue

Get the value of the item as a CharSequence. This is in some cases more efficient than the version of the method that returns a String.

Specified by:

getStringValueCS in interface Item

Specified by:

getStringValueCS in interface ValueRepresentation

Overrides:

getStringValueCS in class AtomicValue

Returns:

the string value of the item

See Also:

Item.getStringValue()

add

public CalendarValue add(DurationValue duration)
                  throws XPathException

Add a duration to this date/time value

Specified by:

add in class CalendarValue

Parameters:

duration - the duration to be added (which might be negative)

Returns:

a new date/time value representing the result of adding the duration. The original object is not modified.

Throws:

XPathException

adjustTimezone

public CalendarValue adjustTimezone(int tz)

Return a new date, time, or dateTime with the same normalized value, but in a different timezone

Specified by:

adjustTimezone in class CalendarValue

Parameters:

tz - the new timezone, in minutes

Returns:

the date/time in the new timezone
