/**
|
|
83 |
* Base class for a serializer supporting both DOM and SAX pretty
|
|
84 |
* serializing of XML/HTML/XHTML documents. Derives classes perform
|
|
85 |
* the method-specific serializing, this class provides the common
|
|
86 |
* serializing mechanisms.
|
|
87 |
* <p>
|
|
88 |
* The serializer must be initialized with the proper writer and
|
|
89 |
* output format before it can be used by calling {@link #setOutputCharStream}
|
|
90 |
* or {@link #setOutputByteStream} for the writer and {@link #setOutputFormat}
|
|
91 |
* for the output format.
|
|
92 |
* <p>
|
|
93 |
* The serializer can be reused any number of times, but cannot
|
|
94 |
* be used concurrently by two threads.
|
|
95 |
* <p>
|
|
96 |
* If an output stream is used, the encoding is taken from the
|
|
97 |
* output format (defaults to <tt>UTF-8</tt>). If a writer is
|
|
98 |
* used, make sure the writer uses the same encoding (if applies)
|
|
99 |
* as specified in the output format.
|
|
100 |
* <p>
|
|
101 |
* The serializer supports both DOM and SAX. DOM serializing is done
|
|
102 |
* by calling {@link #serialize(Document)} and SAX serializing is done by firing
|
|
103 |
* SAX events and using the serializer as a document handler.
|
|
104 |
* This also applies to derived class.
|
|
105 |
* <p>
|
|
106 |
* If an I/O exception occurs while serializing, the serializer
|
|
107 |
* will not throw an exception directly, but only throw it
|
|
108 |
* at the end of serializing (either DOM or SAX's {@link
|
|
109 |
* org.xml.sax.DocumentHandler#endDocument}.
|
|
110 |
* <p>
|
|
111 |
* For elements that are not specified as whitespace preserving,
|
|
112 |
* the serializer will potentially break long text lines at space
|
|
113 |
* boundaries, indent lines, and serialize elements on separate
|
|
114 |
* lines. Line terminators will be regarded as spaces, and
|
|
115 |
* spaces at beginning of line will be stripped.
|
|
116 |
* <p>
|
|
117 |
* When indenting, the serializer is capable of detecting seemingly
|
|
118 |
* element content, and serializing these elements indented on separate
|
|
119 |
* lines. An element is serialized indented when it is the first or
|
|
120 |
* last child of an element, or immediate following or preceding
|
|
121 |
* another element.
