      • unicodeToString

        public static java.lang.CharSequence unicodeToString​(SequenceIterator chars,
                                                             java.util.function.IntPredicate checker)
                                                      throws XPathException
        Return the Unicode string corresponding to a given sequence of Unicode code values
        Parameters:
        chars - iterator delivering the characters as integer values
        checker - used to test whether a character is valid in the appropriate XML version
        Returns:
        the sequence of characters as a CharSequence
        Throws:
        XPathException - if any of the integers is not the codepoint of a valid XML character
      • call

        public StringValue call​(XPathContext context,
                                Sequence[] arguments)
                         throws XPathException
        Evaluate the expression
        Specified by:
        call in interface Callable
        Specified by:
        call in interface Function
        Parameters:
        context - the dynamic evaluation context
        arguments - the values of the arguments, supplied as Sequences
        Returns:
        the result of the evaluation, in the form of a Sequence
        Throws:

      • getStreamerName

        public java.lang.String getStreamerName()
        Description copied from class: SystemFunction
        Get a name that identifies the class that can be used to evaluate this function in streaming mode, that is, supplying one item or event at a time as it is delivered by the parser. Special streaming support is generally available in Saxon-EE for all system functions that take a sequence as their argument.
        Overrides:
        getStreamerName in class SystemFunction
        Returns:
        a name that identifies a class that supports streamed evaluation of this system function, or null if no such class is available. The mapping of names to classes is defined in the Saxon-EE class StreamerMap. In non-streaming Saxon editions (HE and PE) the method always returns null.
