Field Detail

_format

protected final OutputFormat _format

The output format associated with this serializer. This will never be a null reference. If no format was passed to the constructor, the default one for this document type will be used. The format object is never changed by the serializer.

_writer

protected java.io.Writer _writer

The writer to which the document is written.

_dtdWriter

protected java.io.StringWriter _dtdWriter

The DTD writer. When we switch to DTD mode, all output is accumulated in this DTD writer. When we switch out of it, the output is obtained as a string. Must not be reset to null until we're done with the document.

_docWriter

protected java.io.Writer _docWriter

Holds a reference to the document writer while we are in DTD mode.

_exception

protected java.io.IOException _exception

Holds the exception thrown by the serializer. Exceptions do not cause the serializer to quit, but are held and one is thrown at the end.

enterDTD

public void enterDTD()
              throws java.io.IOException

This method may be called any number of time but will only have affect the first time it's called. To exist DTD state and get the accumulated DTD, call leaveDTD().

leaveDTD

public java.lang.String leaveDTD()

Called by the root element to leave DTD mode and if any DTD parts were printer, will return a string with their textual content.

               throws java.io.IOException
