BlobReportContentHandler

BlobReportContentHandler(File outfile)

Implements standard ContentHandler methods, writes to the file specified by the outfile parameter and marks property elements to be written as CDATA.

Method Detail

startPrefixMapping

public void startPrefixMapping(String prefix,
                               String uri)
                        throws SAXException

Throws:

SAXException

endPrefixMapping

public void endPrefixMapping(String prefix)
                      throws SAXException

Throws:

SAXException

ignorableWhitespace

public void ignorableWhitespace(char[] ch,
                                int start,
                                int length)
                         throws SAXException

Throws:

SAXException

processingInstruction

public void processingInstruction(String target,
                                  String data)
                           throws SAXException

Throws:

SAXException

skippedEntity

public void skippedEntity(String name)
                   throws SAXException

Throws:

SAXException

startDocument

public void startDocument()
                   throws SAXException

Throws:

SAXException

doStartDocument

public void doStartDocument()
                     throws SAXException

Called at the beginning of the document rather than the usual startDocument(). The reason for this is because many file are being converted into one document and the calls to startDocument() are ignored.

Throws:

SAXException

endDocument

public void endDocument()
                 throws SAXException

Throws:

SAXException

doEndDocument

public void doEndDocument()
                   throws SAXException

Called at the end of the document rather than the usual endDocument(). The reason for this is because many file are being converted into one document and the calls to endDocument() are ignored.

Throws:

SAXException

characters

public void characters(char[] ch,
                       int start,
                       int length)
                throws SAXException

Throws:

SAXException

startElement

public void startElement(String namespaceURI,
                         String localName,
                         String qName,
                         Attributes atts)
                  throws SAXException

Traps the instance id, property name, and class name being processed. Only writes instance elements if an exception is encountered while de-serializing.

Throws:

SAXException

endElement

public void endElement(String uri,
                       String localName,
                       String qName)
                throws SAXException

De-serialize the object if this is an Instance element.

Throws:

SAXException

showStackTrace

private void showStackTrace(Throwable e)
                     throws SAXException

This gets called when there is a de-serialization problem. Start an instance element, if it hasn't already been done; Start a property element, using the stack trace for its value End the property element. Do not end the instance element because there could be more properties coming for this instance.

Throws:

SAXException

writeEmptyElement

private void writeEmptyElement(String uri_,
                               String status_)
                        throws SAXException

Throws:

SAXException

startInstanceIfNeeded

private void startInstanceIfNeeded()
                            throws SAXException

Throws:

SAXException

makeObject

private String makeObject(String str)
                   throws IOException,
                          ClassNotFoundException,
                          Throwable

De-serialize the object. ClassNotFoundException will be thrown if there is a mis-match.

Throws:

ClassNotFoundException

IOException

Throwable

makeString

private void makeString(char[] ch,
                        int start,
                        int length)

Collect the value being read for the Property.

isClassQueueEntry

private boolean isClassQueueEntry(String className)
                           throws RuntimeException

Throws:

RuntimeException
