Package xj3d.filter

Class MaterialFilter

java.lang.Object

xj3d.filter.AbstractFilter

xj3d.filter.MaterialFilter

All Implemented Interfaces:

BinaryContentHandler, ContentHandler, ProtoHandler, RouteHandler, ScriptHandler, StringContentHandler

public class MaterialFilter
extends AbstractFilter

Search for Appearance nodes which do not specify a Material node, and add material Material { diffuseColor ... } to those nodes. The diffuse color for the Material node can be specified using -diffuse a b c, for example -diffuse 1.0 0.8 0.2 By default, a 0.8 0.8 0.8 value will be supplied (and the default value will be stripped from the output by the default output processor).

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 AbstractFilter

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.

startField

public void startField(String name)
                throws SAVException,
VRMLException

Notification of a field declaration. This notification is only called if it is a standard node. If the node is a script or PROTO declaration then the ScriptHandler or ProtoHandler methods are used.

Specified by:

startField in interface ContentHandler

Overrides:

startField in class AbstractFilter

Parameters:

name - The name of the field declared

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 AbstractFilter

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 - 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 AbstractFilter

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.

fieldValue

public void fieldValue(String value)
                throws SAVException,
VRMLException

The value of a normal field. This is a string that represents the entire value of the field. MFStrings will have to be parsed. This is a terminating call for startField as well. The next call will either be another startField() or endNode().

If this field is an SFNode with a USE declaration you will have the useDecl(String) method called rather than this method.

Specified by:

fieldValue in interface BinaryContentHandler

Specified by:

fieldValue in interface StringContentHandler

Overrides:

fieldValue in class AbstractFilter

Parameters:

value - The value of this field

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 AbstractFilter

Parameters:

args - The array of argument parameters.
