Constructor Details

SurfaceGifitXMLHandler

public SurfaceGifitXMLHandler(FileInfoSurfaceGiftiXML_WM fInfo)

Creates a new SurfaceXMLHandler object.

Parameters:

fInfo - FileInfo for storing the file data into.

Method Details

characters

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

Text data callback from parser. If the parser is not validating, this method can report whitespace. We ignore strings that are entirely whitespace.

Specified by:

characters in interface ContentHandler

Overrides:

characters in class DefaultHandler

Parameters:

ch - Character array

start - Start of data in array.

length - Length of data in array.

endDocument

public void endDocument()
                 throws SAXException

Do nothing.

Specified by:

endDocument in interface ContentHandler

Overrides:

endDocument in class DefaultHandler

Throws:

SAXException - never happens

endElement

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

Called by parser when the end of an element is reached in the document.

Specified by:

endElement in interface ContentHandler

Overrides:

endElement in class DefaultHandler

Parameters:

namespaceURI - the namespace uri

localName - the element name

qName - the qualified name

Throws:

SAXException - if a problem is encountered during parsing

getCoordinate

public Vector<WildMagic.LibFoundation.Mathematics.Vector3f> getCoordinate(String elementBuffer)

Parse the coordinate point value from the section.

Parameters:

elementBuffer - buffer hold the whole coordinate data

Returns:

coords coordinate vector that hold the 3D positions.

getConnectivity

public Vector<Integer> getConnectivity(String elementBuffer)

Parse the connectivity index from the section.

Parameters:

elementBuffer -

Returns:

getColorString

public String getColorString(WildMagic.LibFoundation.Mathematics.ColorRGB kColor)

Called when writing the surface.xml file: Converts the input Color3f to a String for writing:

Parameters:

kColor - color object

Returns:

the color in string format

skippedEntity

public void skippedEntity(String name)

Do nothing but show the entity we skipped.

Specified by:

skippedEntity in interface ContentHandler

Overrides:

skippedEntity in class DefaultHandler
