writeAsEncodedUnicode

public void writeAsEncodedUnicode(java.io.Writer writer)
                           throws javax.xml.stream.XMLStreamException

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 javax.xml.stream.events.XMLEvent

Parameters:

writer - The writer that will output the data

Throws:

javax.xml.stream.XMLStreamException - if there is a fatal error writing the event

writeAsEncodedUnicodeEx

protected abstract void writeAsEncodedUnicodeEx(java.io.Writer writer)
                                         throws java.io.IOException,
                                                javax.xml.stream.XMLStreamException

Helper method in order to expose IOException.

Parameters:

writer - The writer that will output the data

Throws:

javax.xml.stream.XMLStreamException - if there is a fatal error writing the event

java.io.IOException - if there is an IO error

charEncode

protected void charEncode(java.io.Writer writer,
                          java.lang.String data)
                   throws java.io.IOException

Helper method to escape < > & for characters event and quotes, lt and amps for Entity

Throws:

java.io.IOException
