All Implemented Interfaces:

BinaryContentHandler, ContentHandler, ProtoHandler, RouteHandler, ScriptHandler, StringContentHandler

public class USERedundantNodeFilter
extends CommonEncodedBaseFilter

For the specified nodes, compare like nodes for equivalence. DEF and USE equivalent nodes as possible.

Nodes that are already DEF'ed are ignored. Default values for node fields are not considered in the determination of equivalence. If one node does not initialize a field and another node initializes that field to a default value - they are NOT considered to be equivalent.

Filter Options

nodeName "name0 name1 name2" The nodes to check
or
nodeName name0,name1,name2 The nodes to check

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

setArguments

public void setArguments(String[] args)

Set the argument parameters to control the filter operation.

Overrides:

setArguments in class BaseFilter

Parameters:

args - The array of argument parameters.
