startElement

public void startElement(Object type)

Specified by:

startElement in interface Consumer

Specified by:

endElement in interface Consumer

Overrides:

endElement in class PrintConsumer

writeObject

public void writeObject(Object v)

Specified by:

writeObject in interface Consumer

Overrides:

writeObject in class PrintConsumer

write

public void write(CharSequence str,
                  int start,
                  int length)

Specified by:
