      • adjustTimezone

        public TimeValue adjustTimezone​(int timezone)
        Return a new time with the same normalized value, but in a different timezone. This is called only for a TimeValue that has an explicit timezone
        Specified by:

        Parameters:
        timezone - the new timezone offset, in minutes
        Returns:
        the time in the new timezone. This will be a new TimeValue unless no change was required to the original value
      • getComponent

        public AtomicValue getComponent​(AccessorFn.Component component)
                                 throws XPathException
        Get a component of the value. Returns null if the timezone component is requested and is not present.
        Overrides:
        getComponent in class AtomicValue
        Parameters:
        component - the required component
        Returns:
        the value of the requested component of this value
        Throws:
        XPathException - if a dynamic error occurs
      • getXPathComparable

        public XPathComparable getXPathComparable​(StringCollator collator,
                                                  int implicitTimezone)
                                           throws NoDynamicContextException
        Description copied from class: AtomicValue
        Get an object value that implements the XPath equality and ordering comparison semantics for this value. A collation is supplied for comparing strings, and an implicit timezone for comparing date/time values that have no saved timezone. An atomic value may return itself as the result, provided that its ordering rules are independent of the collation and timezone, and provided that it implements the XPathComparable interface: which means that its compareTo, equals, and hashCode methods must be compatible with the rules for XPath value comparisons.
        Overrides:
        getXPathComparable in class CalendarValue
        Parameters:
        collator - the collation to be used when comparing strings
        implicitTimezone - the implicit timezone in the dynamic context, used when comparing dates/times with and without timezone
        Returns:
        an Object that implements the XPath value comparison semantics with respect to this atomic value. For an atomic type that is not ordered (according to XPath rules), return null.
        Throws:
        NoDynamicContextException - if the supplied implicit timezone is "NO_TIMEZONE" (meaning unknown), and the implicit timezone is actually required because the value in question is a date/time value with no timezone. This can cause a failure to evaluate expressions statically (because the implicit timezone is not known statically), and it will then be caught, meaning that the expression has to be evaluated dynamically.
      • compareTo

        public int compareTo​(XPathComparable other)
        Compare the value to another dateTime value
        Specified by:
        compareTo in interface java.lang.Comparable<XPathComparable>
        Parameters:
        other - The other dateTime value
        Returns:
        negative value if this one is the earler, 0 if they are chronologically equal, positive value if this one is the later. For this purpose, dateTime values with an unknown timezone are considered to be UTC values (the Comparable interface requires a total ordering).
        Throws:
        java.lang.ClassCastException - if the other value is not a TimeValue (the parameter is declared as Object to satisfy the Comparable interface)
      • compareTo

        public int compareTo​(CalendarValue other,
                             int implicitTimezone)
                      throws NoDynamicContextException
        Compare the value to another dateTime value
        Specified by:
        compareTo in class CalendarValue
        Parameters:
        other - The other dateTime value
        implicitTimezone - The implicit timezone assumed for a value with no timezone
        Returns:
        negative value if this one is the earler, 0 if they are chronologically equal, positive value if this one is the later. For this purpose, dateTime values with an unknown timezone are considered to be UTC values (the Comparable interface requires a total ordering).
        Throws:
        java.lang.ClassCastException - if the other value is not a DateTimeValue (the parameter is declared as Object to satisfy the Comparable interface)
        NoDynamicContextException - if the implicit timezone is required and is not available (because the function is called at compile time)
      • equals

        public boolean equals​(java.lang.Object other)
        Description copied from class: AtomicValue
        The equals() methods on atomic values is defined to follow the semantics of eq when applied to two atomic values. When the other operand is not an atomic value, the result is undefined (may be false, may be an exception). When the other operand is an atomic value that cannot be compared with this one, the method must throw a ClassCastException.

        The hashCode() method is consistent with equals().

        Overrides:
        equals in class AtomicValue
        Parameters:
        other - the other value
        Returns:
        true (in a subclass) if the other operand is an atomic value and the two values are equal as defined by the XPath eq operator
      • hashCode

        public int hashCode()
        Description copied from class: AtomicValue
        Returns a hash code value for the object.
        Overrides:
        hashCode in class AtomicValue
      • add

        public TimeValue add​(DurationValue duration)
                      throws XPathException
        Add a duration to a dateTime
        Specified by:
        add in class CalendarValue
        Parameters:
        duration - the duration to be added (may be negative)
        Returns:
        the new date
        Throws:
        XPathException - if the duration is an xs:duration, as distinct from a subclass thereof
