public TextureTransformFilter()

Basic constructor.

Method Details

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 NewAbstractFilter

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

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 NewAbstractFilter

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 NewAbstractFilter

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 NewAbstractFilter.useDecl(String) method called rather than this method.

Specified by:

fieldValue in interface BinaryContentHandler

Specified by:

fieldValue in interface StringContentHandler

Overrides:

fieldValue in class NewAbstractFilter

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

fieldValue

public void fieldValue(String[] values)
                throws SAVException,
VRMLException

The value of an MFField where the underlying parser knows about how the values are broken up. The parser is not required to support this callback, but implementors of this interface should understand it. The most likely time we will have this method called is for MFString or URL lists. If called, it is guaranteed to split the strings along the SF node type boundaries.

Specified by:

fieldValue in interface StringContentHandler

Overrides:

fieldValue in class NewAbstractFilter

Parameters:

values - The list of string representing the values

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

fieldValue

public void fieldValue(float value)
                throws SAVException,
VRMLException

Set the value of the field at the given index as a float. This would be used to set SFFloat field types.

Specified by:

fieldValue in interface BinaryContentHandler

Overrides:

fieldValue in class NewAbstractFilter

Parameters:

value - The new value to use for the 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.

fieldValue

public void fieldValue(float[] value,
 int len)
                throws SAVException,
VRMLException

Set the value of the field at the given index as an array of floats. This would be used to set MFFloat, SFVec2f, SFVec3f and SFRotation field types.

Specified by:

fieldValue in interface BinaryContentHandler

Overrides:

fieldValue in class NewAbstractFilter

Parameters:

value - The new value to use for the node

len - The number of valid entries in the value array

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,
 int len)
                throws SAVException,
VRMLException

Set the value of the field at the given index as an array of strings. This would be used to set MFString field types.

Specified by:

fieldValue in interface BinaryContentHandler

Overrides:

fieldValue in class NewAbstractFilter

Parameters:

value - The new value to use for the node

len - The number of valid entries in the value array

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.

setArguments

public void setArguments(String[] args)

Set the argument parameters to control the filter operation.

Overrides:

setArguments in class NewAbstractFilter

Parameters:

args - The array of argument parameters.
