Interface Serializer

All Known Implementing Classes:

SerializerToXML

public interface Serializer

The Serializer interface is implemented by Serializers to publish methods to get and set streams and writers, to set the output properties, and get the Serializer as a ContentHandler or DOMSerializer.

Method Summary

org.xml.sax.ContentHandler	asContentHandler() Return a ContentHandler interface into this serializer.
DOMSerializer	asDOMSerializer() Return a DOMSerializer interface into this serializer.
Properties	getOutputFormat() Returns the output format for this serializer.
OutputStream	getOutputStream() Get the output stream where the events will be serialized to.
Writer	getWriter() Get the character stream where the events will be serialized to.
boolean	reset() Resets the serializer.
void	setOutputFormat(Properties format) Specifies an output format for this serializer.
void	setOutputStream(OutputStream output) Specifies an output stream to which the document should be serialized.
void	setWriter(Writer writer) Specifies a writer to which the document should be serialized.

Method Detail

setOutputStream

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 output Properties is used, or if no encoding was specified, the default for the selected output method.

Parameters:

output - The output stream

getOutputStream

public OutputStream getOutputStream()

Get the output stream where the events will be serialized to.

Returns:

reference to the result stream, or null of only a writer was set.

setWriter

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 output Properties must be identical to the output format used with the writer.

Parameters:

writer - The output writer stream

getWriter

public Writer getWriter()

Get the character stream where the events will be serialized to.

Returns:

Reference to the result Writer, or null.

setOutputFormat

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.

Parameters:

format - The output format to use

getOutputFormat

public Properties getOutputFormat()

Returns the output format for this serializer.

Returns:

The output format in use

asContentHandler

public org.xml.sax.ContentHandler asContentHandler()
                                            throws IOException

Return a ContentHandler interface into this serializer. If the serializer does not support the ContentHandler interface, it should return null.

Returns:

A ContentHandler interface into this serializer, or null if the serializer is not SAX 2 capable

Throws:

IOException - An I/O exception occured

asDOMSerializer

public DOMSerializer asDOMSerializer()
                              throws IOException

Return a DOMSerializer interface into this serializer. If the serializer does not support the DOMSerializer interface, it should return null.

Returns:

A DOMSerializer interface into this serializer, or null if the serializer is not DOM capable

Throws:

IOException - An I/O exception occured

reset

public boolean reset()

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 use the existing output format and output stream.

Returns:

True if serializer has been reset and can be reused
