TriangleCountInfoFilter

public TriangleCountInfoFilter()

Create an instance of the filter.

Method Details

endDocument

public void endDocument()
                 throws SAVException,
VRMLException

Declaration of the end of the document. There will be no further parsing and hence events after this.

Specified by:

endDocument in interface ContentHandler

Overrides:

endDocument in class CommonEncodedBaseFilter

Throws:

SAVException - This call is taken at the wrong time in the structure of the document

VRMLException - The content provided is invalid for this part of the document or can't be parsed

startNode

public void startNode(String name,
 String defName)
               throws SAVException,
VRMLException

Notification of the start of a node. This is the opening statement of a node and it's DEF name. USE declarations are handled in a separate method.

Specified by:

startNode in interface ContentHandler

Overrides:

startNode in class CommonEncodedBaseFilter

Parameters:

name - The name of the node that we are about to parse

defName - The string associated with the DEF name. Null if not given for this node.

Throws:

SAVException - This call is taken at the wrong time in the structure of the document

VRMLException - The content provided is invalid for this part of the document or can't be parsed

endNode

public void endNode()
             throws SAVException,
VRMLException

Notification of the end of a node declaration.

Specified by:

endNode in interface ContentHandler

Overrides:

endNode in class CommonEncodedBaseFilter

Throws:

SAVException - This call is taken at the wrong time in the structure of the document.

VRMLException - This call is taken at the wrong time in the structure of the document.

getTriangleCount

public int getTriangleCount()

Get the triangle count for the whole stream.

Specified by:

getTriangleCount in interface TriangleCounter

Returns:

The triangle count.
