This method will write the XMLEvent as per the XML 1.0 specification as Unicode characters. No indentation or whitespace should be outputted. Any user defined event type SHALL have this method called when being written to on an output stream. Built in Event types MUST implement this method, but implementations MAY choose not call these methods for optimizations reasons when writing out built in Events to an output stream. The output generated MUST be equivalent in terms of the infoset expressed.

Specified by:

writeAsEncodedUnicode in interface XMLEvent

Parameters:

writer - The writer that will output the data

Throws:

XMLStreamException

doWriteAsEncodedUnicode
