// Sep 14, 2000:
//  Fixed comments to preserve whitespaces and add a line break
//  when indenting. Reported by Gervase Markham <gerv@gerv.net>
// Sep 14, 2000:
//  Fixed serializer to report IO exception directly, instead at
//  the end of document processing.
//  Reported by Patrick Higgins <phiggins@transzap.com>
// Sep 13, 2000:
//   CR in character data will print as &#0D;
// Aug 25, 2000:
//   Fixed processing instruction printing inside element content
//   to not escape content. Reported by Mikael Staldal
//   <d96-mst@d.kth.se>

/**
 * Base class for a serializer supporting both DOM and SAX pretty
 * serializing of XML/HTML/XHTML documents. Derives classes perform
 * the method-specific serializing, this class provides the common
 * serializing mechanisms.
 * <p>
 * The serializer must be initialized with the proper writer and
 * output format before it can be used by calling {@link #setOutputCharStream} 
 * or {@link #setOutputByteStream} for the writer and {@link #setOutputFormat}
 * for the output format.
 * <p>
 * The serializer can be reused any number of times, but cannot
 * be used concurrently by two threads.
 * <p>
 * If an output stream is used, the encoding is taken from the
 * output format (defaults to <tt>UTF-8</tt>). If a writer is
 * used, make sure the writer uses the same encoding (if applies)
 * as specified in the output format.
 * <p>
 * The serializer supports both DOM and SAX. DOM serializing is done
 * by calling {@link #serialize(Document)} and SAX serializing is done by firing
 * SAX events and using the serializer as a document handler.
 * This also applies to derived class.
 * <p>
 * If an I/O exception occurs while serializing, the serializer
 * will not throw an exception directly, but only throw it
 * at the end of serializing (either DOM or SAX's {@link
 * org.xml.sax.DocumentHandler#endDocument}.
 * <p>
 * For elements that are not specified as whitespace preserving,
 * the serializer will potentially break long text lines at space
 * boundaries, indent lines, and serialize elements on separate
 * lines. Line terminators will be regarded as spaces, and
 * spaces at beginning of line will be stripped.
 * <p>
 * When indenting, the serializer is capable of detecting seemingly
 * element content, and serializing these elements indented on separate
 * lines. An element is serialized indented when it is the first or
 * last child of an element, or immediate following or preceding
 * another element.
 *
 * @deprecated This class was deprecated in Xerces 2.9.0. It is recommended 
 * that new applications use the DOM Level 3 LSSerializer or JAXP's Transformation 
 * API for XML (TrAX) for serializing XML. See the Xerces documentation for more 
 * information.
