com.icl.saxon.output.Emitter
com.icl.saxon.output.ContentHandlerProxy
A ContentHandlerProxy is an Emitter that filters data before passing it to an
underlying SAX2 ContentHandler. Relevant events (notably comments) can also be
fed to a LexicalHandler.
Note that in general the output passed to an Emitter
corresponds to an External General Parsed Entity. A SAX2 ContentHandler only expects
to deal with well-formed XML documents, so we only pass it the contents of the first
element encountered.

Method Details
-
setUnderlyingContentHandler
Set the underlying content handler. This call is mandatory before using the Emitter. -
setOutputProperties
Set the output properties- Overrides:
setOutputProperties
in classEmitter
-
setLexicalHandler
Set the Lexical Handler to be used. If called, this must be called AFTER setUnderlyingContentHandler() -
setRequireWellFormed
public void setRequireWellFormed(boolean wellFormed) Indicate whether the content handler can handle a stream of events that is merely well-balanced, or whether it can only handle a well-formed sequence. -
setDocumentLocator
Set Document Locator- Overrides:
setDocumentLocator
in classEmitter
-
startDocument
Start of document- Specified by:
startDocument
in classEmitter
- Throws:
TransformerException
-
endDocument
End of document- Specified by:
endDocument
in classEmitter
- Throws:
TransformerException
-
startElement
public void startElement(int nameCode, Attributes atts, int[] namespaces, int nscount) throws TransformerException Start of element- Specified by:
startElement
in classEmitter
- Parameters:
namespaces
- Array of namespace codes identifying the namespace prefix/uri pairs associated with this elementnscount
- Number of significant entries within namespaces array- Throws:
TransformerException
-
endElement
End of element- Specified by:
endElement
in classEmitter
- Throws:
TransformerException
-
characters
Character data- Specified by:
characters
in classEmitter
- Throws:
TransformerException
-
notifyNotWellFormed
The following function notifies the content handler, by means of a processing instruction, that the output is not a well-formed document. If the content handler responds with an exception containing the message "continue" (this is the only way it can get information back) then further events are notified, otherwise they are suppressed.- Throws:
SAXException
-
processingInstruction
Processing Instruction- Specified by:
processingInstruction
in classEmitter
- Throws:
TransformerException
-
comment
Output a comment. Passes it on to the ContentHandler provided that the ContentHandler is also a SAX2 LexicalHandler.- Specified by:
comment
in classEmitter
- Throws:
TransformerException
-
setEscaping
public void setEscaping(boolean escaping) Switch escaping on or off. This is called when the XSLT disable-output-escaping attribute is used to switch escaping on or off. It is not called for other sections of output (e.g. element names) where escaping is inappropriate. The action, as defined in JAXP 1.1, is to notify the request to the Content Handler using a processing instruction.- Overrides:
