public interface Serializer
java.util.Properties props =
OutputPropertiesFactory.getDefaultMethodProperties(Method.TEXT);
Serializer ser = SerializerFactory.getSerializer(props);
java.io.PrintStream ostream = System.out;
ser.setOutputStream(ostream);
// Provide the SAX input events
ContentHandler handler = ser.asContentHandler();
handler.startDocument();
char[] chars = { 'a', 'b', 'c' };
handler.characters(chars, 0, chars.length);
handler.endDocument();
ser.reset(); // get ready to use the serializer for another document
// of the same output method (TEXT).
As an alternate to supplying a series of SAX events as input through the
ContentHandler interface, the input to serialize may be given as a DOM.
For example:
org.w3c.dom.Document inputDoc;
org.apache.xml.serializer.Serializer ser;
java.io.Writer owriter;
java.util.Properties props =
OutputPropertiesFactory.getDefaultMethodProperties(Method.XML);
Serializer ser = SerializerFactory.getSerializer(props);
owriter = ...; // create a writer to serialize the document to
ser.setWriter( owriter );
inputDoc = ...; // create the DOM document to be serialized
DOMSerializer dser = ser.asDOMSerializer(); // a DOM will be serialized
dser.serialize(inputDoc); // serialize the DOM, sending output to owriter
ser.reset(); // get ready to use the serializer for another document
// of the same output method.
This interface is a public API.

public ContentHandler asContentHandler()
throws IOExceptionReturn aContentHandlerinterface to provide SAX input to. Through the returned object the document to be serailized, as a series of SAX events, can be provided to the serialzier. If the serializer does not support theContentHandlerinterface, it will return null. In principle only one of asDOMSerializer() or asContentHander() should be called.
- Returns:
- A
ContentHandlerinterface into this serializer, or null if the serializer is not SAX 2 capable
public DOMSerializer asDOMSerializer() throws IOException
Return aDOMSerializerinterface into this serializer. Through the returned object the document to be serialized, a DOM, can be provided to the serializer. If the serializer does not support theDOMSerializerinterface, it should return null. In principle only one of asDOMSerializer() or asContentHander() should be called.
- Returns:
- A
DOMSerializerinterface into this serializer, or null if the serializer is not DOM capable
public Properties getOutputFormat()
Returns the output format properties for this serializer.
- Returns:
- The output format key/value pairs in use.
public OutputStream getOutputStream()
Get the output stream where the events will be serialized to.
- Returns:
- reference to the result stream, or null if only a writer was set.
public Writer getWriter()
Get the character stream where the events will be serialized to.
- Returns:
- Reference to the result Writer, or null.
public boolean reset()
This method resets the serializer. If this method returns true, the serializer may be used for subsequent serialization of new documents. It is possible to change the output format and output stream prior to serializing, or to reuse the existing output format and output stream or writer.
- Returns:
- True if serializer has been reset and can be reused
public void setOutputFormat(Properties format)
Specifies an output format for this serializer. It the serializer has already been associated with an output format, it will switch to the new format. This method should not be called while the serializer is in the process of serializing a document. The standard property keys supported are: "method", "version", "encoding", "omit-xml-declaration", "standalone", doctype-public", "doctype-system", "cdata-section-elements", "indent", "media-type". These property keys and their values are described in the XSLT recommendation, seeXSLT 1.0 recommendationThe non-standard property keys supported are defined inOutputPropertiesFactory. This method can be called multiple times before a document is serialized. Each time it is called more, or over-riding property values, can be specified. One property value that can not be changed is that of the "method" property key. The value of the "cdata-section-elements" property key is a whitespace separated list of elements. If the element is in a namespace then value is passed in this format: {uri}localName If the "cdata-section-elements" key is specified on multiple calls to this method the set of elements specified in the value is not replaced from one call to the next, but it is cumulative across the calls.
- Parameters:
format- The output format to use, as a set of key/value pairs.
public void setOutputStream(OutputStream output)
Specifies an output stream to which the document should be serialized. This method should not be called while the serializer is in the process of serializing a document. The encoding specified in the outputPropertiesis used, or if no encoding was specified, the default for the selected output method. Only one of setWriter() or setOutputStream() should be called.
- Parameters:
output- The output stream
public void setWriter(Writer writer)
Specifies a writer to which the document should be serialized. This method should not be called while the serializer is in the process of serializing a document. The encoding specified for the outputPropertiesmust be identical to the output format used with the writer. Only one of setWriter() or setOutputStream() should be called.
- Parameters:
writer- The output writer stream
