/**
|
|
* Implements an XML serializer supporting both DOM and SAX pretty
|
|
* serializing. For usage instructions see {@link Serializer}.
|
|
* <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. SAX serializing is done by firing
|
|
* SAX events and using the serializer as a document handler. DOM serializing is done
|
|
* by calling {@link #serialize(Document)} or by using DOM Level 3
|
|
* {@link org.w3c.dom.ls.DOMSerializer} and
|
|
* serializing with {@link org.w3c.dom.ls.DOMSerializer#write},
|
|
* {@link org.w3c.dom.ls.DOMSerializer#writeToString}.
|
|
* <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.
