[xep-support] Trace output during rendering

[Smolders, Eric]

Hi David,

I have read paragraph #4 several times but I don't understand how to attach
the custom document handler to the logger.
This is what I have tried:

  class cusHandler implements org.xml.sax.DocumentHandler
  {
    public synchronized void startDocument() throws org.xml.sax.SAXException
    {
    }

    public synchronized void endDocument() throws org.xml.sax.SAXException
    {
    }

    public synchronized void startElement(java.lang.String name,
                                          org.xml.sax.AttributeList atts)
throws org.xml.sax.SAXException
    {
    }
    
    public synchronized void endElement(java.lang.String name) throws
org.xml.sax.SAXException
    {
    }

    public synchronized void characters(char[] buffer, int start, int
length) throws org.xml.sax.SAXException
    {
    }

    public synchronized void ignorableWhitespace(char[] buffer, int start,
int length) throws org.xml.sax.SAXException
    {
    }

    public synchronized void processingInstruction(java.lang.String s1,
                                                   java.lang.String s2)
throws org.xml.sax.SAXException
    {
    }

    public synchronized void setDocumentLocator(org.xml.sax.Locator locator)

    {
    }
  }

Then I try to attach the custom handler to the logger in this way:

          cusHandler handler = new cusHandler();
 
com.renderx.FO2PDF.L.EventLogger.logger().setDocumentHandler(handler);

These calls are done after XEP is initialized.

After I have implemented this code, the same logging still occurs in the
output file.

Another question: when will the deprecated class DocumentHandler be replace
by the new class ContentHandler or when will deprecated Classes and methods
be replaced by the new ones in XEP?

Regards,

Eric Smolders

Yes.

The logging facility is fully configurable, and you can pass a dummy
logger to the engine. Details are in applications.pdf, "Using XEP 2.7 in
Java Applications", paragraph #4, "Logging Facility".
