        Return a StringItem corresponding to a given sequence of Unicode code values
        chars - iterator delivering the characters as integer values
        checker - used to test whether a character is valid in the appropriate XML version
        the sequence of characters as a StringItem
        XPathException - if any of the integers is not the codepoint of a valid XML character

      • 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.
        getStreamerName in class SystemFunction
        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.
