Method Detail

printText

private void printText(String methodName)

printText

private void printText(String methodName,
             String itemName)

printAttributes

private void printAttributes(Attributes atts)

setDocumentLocator

public void setDocumentLocator(Locator locator)

Specified by:

setDocumentLocator in interface ContentHandler

startDocument

public void startDocument()
                   throws SAXException

Called by the parser when the start of the document is encountered.

Initializes fields used in parsing document.

Specified by:

startDocument in interface ContentHandler

Throws:

SAXException

endDocument

public void endDocument()
                 throws SAXException

Called by the parser when the end of the document is encountered.

Specified by:

endDocument in interface ContentHandler

Throws:

SAXException

startPrefixMapping

public void startPrefixMapping(String prefix,
                      String uri)
