void |
checkValidInJavascript()
Check that the value can be handled in Saxon-JS
|
int |
compareTo(CalendarValue other,
int implicitTimezone)
Compare this value to another value of the same type, using the supplied context object
to get the implicit timezone if required.
|
boolean |
equals(java.lang.Object o)
The equals() methods on atomic values is defined to follow the semantics of eq when applied
to two atomic values.
|
java.util.GregorianCalendar |
getCalendar()
Get a Java Calendar object that represents this date/time value.
|
AtomicValue |
getComponent(AccessorFn.Component component)
Get a component of the value.
|
byte |
getDay()
Get the day component of the date (in local form)
|
byte |
getMonth()
Get the month component of the date (in local form)
|
java.lang.Comparable |
getSchemaComparable()
Get a Comparable value that implements the XML Schema ordering comparison semantics for this value.
|
int |
getYear()
Get the year component of the date (in local form)
|
int |
hashCode() |
static boolean |
isLeapYear(int year)
Test whether a year is a leap year
|
static boolean |
isValidDate(int year,
int month,
int day)
Determine whether a given date is valid
|
protected static ConversionResult |
setLexicalValue(GDateValue d,
java.lang.CharSequence s,
boolean allowYearZero)
Initialize the DateValue using a character string in the format yyyy-mm-dd and an optional time zone.

The hashCode() method is consistent with equals().
This implementation performs a context-free comparison: it fails with ClassCastException if one value has a timezone and the other does not.

public java.lang.Comparable getSchemaComparable()
AtomicValue
In the case of data types that are partially ordered, the returned Comparable extends the standard
semantics of the compareTo() method by returning the value SequenceTool.INDETERMINATE_ORDERING
when there
is no defined order relationship between two given values. This value is also returned when two values
of different types are compared.
