void	endElement(java.lang.String uri, java.lang.String name, java.lang.String qName) Handles the end of an element.
void	endPrefixMapping(java.lang.String prefix) End a namepace prefix to uri mapping
void	setDocumentLocator(org.xml.sax.Locator locator) Sets the locator in the project helper for future reference.
void	startElement(java.lang.String uri, java.lang.String tag, java.lang.String qname, org.xml.sax.Attributes attrs) Handles the start of a project element.

Method Detail

startElement

public void startElement(java.lang.String uri,
                         java.lang.String tag,
                         java.lang.String qname,

                  throws org.xml.sax.SAXParseException

Handles the start of a project element. A project handler is created and initialised with the element name and attributes.

Parameters:

uri - The namespace uri for this element.

tag - The name of the element being started. Will not be null.

qname - The qualified name for this element.

attrs - Attributes of the element being started. Will not be null.

Throws:

org.xml.sax.SAXParseException - if the tag given is not "project"

setDocumentLocator

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

Sets the locator in the project helper for future reference.

Parameters:

locator - The locator used by the parser. Will not be null.

endElement

public void endElement(java.lang.String uri,
                       java.lang.String name,
                       java.lang.String qName)
                throws org.xml.sax.SAXException

Handles the end of an element. Any required clean-up is performed by the onEndElement() method and then the original handler is restored to the parser.

Parameters:

uri - The namespace URI for this element.

name - The name of the element which is ending. Will not be null.

qName - The qualified name for this element.

Throws:

org.xml.sax.SAXException - in case of error (not thrown in this implementation)

Parameters:

buf - A character array of the test.

start - The start offset in the array.

count - The number of characters to read.

Throws:

org.xml.sax.SAXParseException - if an error occurs

startPrefixMapping

public void startPrefixMapping(java.lang.String prefix,
                               java.lang.String uri)

Start a namespace prefix to uri mapping

Parameters:

prefix - the namespace prefix

uri - the namespace uri

endPrefixMapping

public void endPrefixMapping(java.lang.String prefix)

End a namepace prefix to uri mapping

Parameters:

prefix - the prefix that is not mapped anymore
