Method Detail

getRootHandler

protected abstract SAXTagHandler getRootHandler(java.lang.String uri,
                                                java.lang.String localName,
                                                java.lang.String name,
                                                org.xml.sax.Attributes atts)
                                         throws org.xml.sax.SAXException
This function is called, when the root element is opened through ContentHandler.startElement(String, String, String, Attributes).

Parameters:
uri - The namespace URI of the received tag.
localName - The name of the tag without any namespace prefix.
name - The fully-qualified name of the tag. This is the tag name, if the namespace URI is null.
atts - Any attributes attached to the child
Returns:
The handler, which processes the child. A null return value tells the SAX parser to ignore the content of the child.
Throws:
org.xml.sax.SAXException - Upon errors processing the data.
