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.
Method Summary |
void | characters(char[] chars, int start, int len)
Character data |
void | comment(char[] ch, int start, int length)
Output a comment. |
void | endDocument()
End of document |
void | endElement(int nameCode)
End of element |
int | getColumnNumber() |
int | getLineNumber() |
String | getPublicId() |
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. |
void | processingInstruction(String target, String data)
Processing Instruction |
void | setDocumentLocator(Locator locator)
Set Document Locator |
void | setEscaping(boolean escaping)
Switch escaping on or off. |
void | setLexicalHandler(LexicalHandler handler)
Set the Lexical Handler to be used. |
void | setOutputProperties(Properties props)
Set the output properties |
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. |
void | setUnderlyingContentHandler(ContentHandler handler)
Set the underlying content handler. |
void | startDocument()
Start of document |
void | startElement(int nameCode, Attributes atts, int[] namespaces, int nscount)
Start of element |
protected ContentHandler handler

protected Locator locator
protected boolean requireWellFormed
public void characters(char[] chars, int start, int len)
Character data
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.
public void endDocument()
End of document
public void endElement(int nameCode)
End of element
public int getColumnNumber()
public int getLineNumber()
public String getPublicId()
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.
public void processingInstruction(String target, String data)
Processing Instruction
public void setDocumentLocator(Locator locator)
Set Document Locator
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.
public void setLexicalHandler(LexicalHandler handler)
Set the Lexical Handler to be used. If called, this must be called AFTER
setUnderlyingContentHandler()
public void setOutputProperties(Properties props)
Set the output properties
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.
public void setUnderlyingContentHandler(ContentHandler handler)
Set the underlying content handler. This call is mandatory before using the Emitter.
public void startDocument()
Start of document
public void startElement(int nameCode, Attributes atts, int[] namespaces, int nscount)
Start of element
