Class ContentHandlerProxy

public class ContentHandlerProxy extends Emitter implements Locator

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.

protected Locator locator

requireWellFormed

protected boolean requireWellFormed

Method Detail

characters

public void characters(char[] chars, int start, int len)
Character data

comment

public void comment(char[] ch, int start, int length)
Output a comment. Passes it on to the ContentHandler provided that the ContentHandler is also a SAX2 LexicalHandler.

endDocument

public void endDocument()
End of document

endElement

public void endElement(int nameCode)
End of element

getColumnNumber

public int getColumnNumber()

getLineNumber

public int getLineNumber()

getPublicId

public String getPublicId()

notifyNotWellFormed

protected void 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.

processingInstruction

public void processingInstruction(String target, String data)
Processing Instruction

setDocumentLocator

public void setDocumentLocator(Locator locator)
Set Document Locator

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.

setLexicalHandler

public void setLexicalHandler(LexicalHandler handler)
Set the Lexical Handler to be used. If called, this must be called AFTER setUnderlyingContentHandler()

setOutputProperties

public void setOutputProperties(Properties props)
Set the output properties

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.

setUnderlyingContentHandler

public void setUnderlyingContentHandler(ContentHandler handler)
Set the underlying content handler. This call is mandatory before using the Emitter.

startDocument

public void startDocument()
Start of document

startElement

public void startElement(int nameCode, Attributes atts, int[] namespaces, int nscount)
Start of element
