Method Details

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 EncodedBaseFilter

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

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 EncodedBaseFilter

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.
