Examples of client.net.sf.saxon.ce.om.StructuredQName

client.net.sf.saxon.ce.om.StructuredQName
This class provides an economical representation of a QName triple (prefix, URI, and localname). The value is stored internally as a character array containing the concatenation of URI, localname, and prefix (in that order) with two integers giving the start positions of the localname and prefix.
Instances of this class are immutable.

     * @return  the name of the function as a lexical QName
