All Implemented Interfaces:

BinaryContentHandler, ContentHandler, ProtoHandler, RouteHandler, ScriptHandler, StringContentHandler

public class FlattenTransformFilter
extends CommonEncodedBaseFilter

Filter for removing transform hierarchies. The transformational components of the Transforms are combined and the coordinates of the children nodes are transformed to retain the information. The end result is a file containing geometry (Shape nodes) without the grouping node.

At present - IndexedTriangleSet, IndexedTriangleStripSet, IndexedTriangleFanSet, and Viewpoint nodes are transformed and output.

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

useDecl

public void useDecl(String defName)
             throws SAVException,
VRMLException

The field value is a USE for the given node name. This is a terminating call for startField as well. The next call will either be another startField() or endNode().

Specified by:

useDecl in interface ContentHandler

Overrides:

useDecl in class CommonEncodedBaseFilter

Parameters:

defName - The name of the DEF string to use

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
