ProxyEmitter

public ProxyEmitter()

Method Detail

setUnderlyingEmitter

public void setUnderlyingEmitter(Emitter emitter)

Set the underlying emitter. This call is mandatory before using the Emitter.

setNamePool

public void setNamePool(NamePool pool)

Set the name pool to be used for all name codes

Specified by:

setNamePool in interface Emitter

setWriter

public void setWriter(java.io.Writer writer)
               throws org.xml.sax.SAXException

Set the Writer to be used. The writer will already be set up to perform any encoding requested. A writer will always be supplied before startDocument() is called.

Specified by:

setWriter in interface Emitter

setCharacterSet

public void setCharacterSet(CharacterSet charset)
                     throws org.xml.sax.SAXException

Set the CharacterSet to be used. The CharacterSet is a property of the encoding, it defines which characters are available in the output encoding. If no character set is supplied, the UnicodeCharacterSet should be assumed.

Specified by:

setCharacterSet in interface Emitter

startDocument

public void startDocument()
                   throws org.xml.sax.SAXException

Start of document

Specified by:

startDocument in interface Emitter

endDocument

public void endDocument()
                 throws org.xml.sax.SAXException

End of document

Specified by:

endDocument in interface Emitter

startElement

public void startElement(int nameCode,
                         org.xml.sax.Attributes attributes,
                         int[] namespaces,
                         int nscount)
                  throws org.xml.sax.SAXException

Start of element

Specified by:

startElement in interface Emitter

Following copied from interface: com.icl.saxon.output.Emitter

Parameters:

namespaces - Array of namespace codes identifying the namespace prefix/uri pairs associated with this element

nscount - Number of significant entries within namespaces array

endElement

public void endElement(int nameCode)
                throws org.xml.sax.SAXException

End of element

Specified by:

endElement in interface Emitter

characters

public void characters(char[] chars,
                       int start,
                       int len)
                throws org.xml.sax.SAXException

Character data

Specified by:

characters in interface Emitter

processingInstruction

public void processingInstruction(java.lang.String target,
                                  java.lang.String data)
                           throws org.xml.sax.SAXException

Processing Instruction

Specified by:

processingInstruction in interface Emitter

comment

public void comment(char[] ch,

Specified by:

setEscaping in interface Emitter

setOutputDetails

public void setOutputDetails(OutputDetails details)
                      throws org.xml.sax.SAXException

Specified by:

setOutputDetails in interface Emitter

Following copied from interface: com.icl.saxon.output.Emitter

Parameters:

details - The details of the required output

setUnparsedEntity

public void setUnparsedEntity(java.lang.String name,
                              java.lang.String uri)
                       throws org.xml.sax.SAXException
