gov.nih.mipav.view.dialogs.MyXMLHandler

All Implemented Interfaces:

ContentHandler, DTDHandler, EntityResolver, ErrorHandler

class MyXMLHandler
extends DefaultHandler

Handle events generated while parsing the XML file. This MyXMLHandler is a special one. We just need to save the Pts from the VOI xml file into one chunk vector. We don't need to save the point coordinates into the VOI structure.

The current XML tag we are parsing.

elementBuffer

private String elementBuffer

The data for the current element being parsed.

sliceNumber

private int sliceNumber

Constructor Details

MyXMLHandler

public MyXMLHandler()

Construct our custom XML data handler.

Parameters:

voi - the VOI we should build from the XML file data

Method Details

getContourVector

public Vector<WildMagic.LibFoundation.Mathematics.Vector3f> getContourVector()

Get the whole contour vector generated from the xml file.

Returns:

contour vector

characters

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

DOCUMENT ME!

Specified by:

characters in interface ContentHandler

Overrides:

characters in class DefaultHandler

Parameters:

ch - char[]

start - int

length - int

endElement

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

Parser calls this when the end tag of each element is reached. Data collected in the elementbuffer is generally saved to the image info.

Specified by:

endElement in interface ContentHandler

Overrides:

endElement in class DefaultHandler

Parameters:

namespaceURI - the namespace (not used)

localName - the current tag we are parsing

qName - ? (not used)

Throws:

SAXException - if there is a problem with the parser

startElement

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

Parser calls this for each element in a document.

Specified by:

startElement in interface ContentHandler

Overrides:

startElement in class DefaultHandler

Parameters:

namespaceURI - the namespace (not used)

localName - the current tag we are parsing

qName - ? (not used)

atts - attributes for the current tag

Throws:

SAXException - if there is a problem with the parser
