Method Detail

startDocument

public void startDocument()
                   throws SAXException
Description copied from interface: ContentHandler
Receive notification of the beginning of a document.

The SAX parser will invoke this method only once, before any other methods in this interface or in DTDHandler (except for setDocumentLocator).

Overrides:
startDocument in class org.xml.sax.helpers.DefaultHandler
Following copied from interface: org.xml.sax.ContentHandler
Throws:
SAXException - Any SAX exception, possibly wrapping another exception.
See Also:
ContentHandler.endDocument()

endDocument

public void endDocument()
                 throws SAXException
Description copied from interface: ContentHandler
Receive notification of the end of a document.

The SAX parser will invoke this method only once, and it will be the last method invoked during the parse. The parser shall not invoke this method until it has either abandoned parsing (because of an unrecoverable error) or reached the end of input.

Overrides:
endDocument in class org.xml.sax.helpers.DefaultHandler
Following copied from interface: org.xml.sax.ContentHandler
Throws:
SAXException - Any SAX exception, possibly wrapping another exception.
See Also:
ContentHandler.startDocument()

startElement

public void startElement(java.lang.String uri,
                         java.lang.String local,
                         java.lang.String qname,
                         Attributes attr)
                  throws SAXException
Description copied from interface: ContentHandler
Receive notification of the beginning of an element.

The Parser will invoke this method at the beginning of every element in the XML document; there will be a corresponding endElement event for every startElement event (even when the element is empty). All of the element's content will be reported, in order, before the corresponding endElement event.

This event allows up to three name components for each element:

  1. the Namespace URI;
  2. the local name; and
  3. the qualified (prefixed) name.

Any or all of these may be provided, depending on the values of the http://xml.org/sax/features/namespaces and the http://xml.org/sax/features/namespace-prefixes properties:

Note that the attribute list provided will contain only attributes with explicit values (specified or defaulted): #IMPLIED attributes will be omitted. The attribute list will contain attributes used for Namespace declarations (xmlns* attributes) only if the http://xml.org/sax/features/namespace-prefixes property is true (it is false by default, and support for a true value is optional).

Overrides:
startElement in class GenericParser
Following copied from interface: org.xml.sax.ContentHandler
Parameters:
uri - The Namespace URI, or the empty string if the element has no Namespace URI or if Namespace processing is not being performed.
localName - The local name (without prefix), or the empty string if Namespace processing is not being performed.
qName - The qualified name (with prefix), or the empty string if qualified names are not available.
atts - The attributes attached to the element. If there are no attributes, it shall be an empty Attributes object.
Throws:
SAXException - Any SAX exception, possibly wrapping another exception.
See Also:
ContentHandler.endElement(java.lang.String, java.lang.String, java.lang.String), Attributes

endElement

public void endElement(java.lang.String uri,
                       java.lang.String local,
                       java.lang.String qname)
                throws SAXException
Description copied from interface: ContentHandler
Receive notification of the end of an element.

The SAX parser will invoke this method at the end of every element in the XML document; there will be a corresponding startElement event for every endElement event (even when the element is empty).

For information on the names, see startElement.

Overrides:
endElement in class GenericParser
Following copied from interface: org.xml.sax.ContentHandler
Parameters:
uri - The Namespace URI, or the empty string if the element has no Namespace URI or if Namespace processing is not being performed.
localName - The local name (without prefix), or the empty string if Namespace processing is not being performed.
qName - The qualified XML 1.0 name (with prefix), or the empty string if qualified names are not available.
Throws:
SAXException - Any SAX exception, possibly wrapping another exception.

                                    Resource predicate,

                             throws ModelException
Overrides:
