public java.lang.String filterAttributeValue(NamedObj container, java.lang.String element, java.lang.String attributeName, java.lang.String attributeValue, java.lang.String xmlFile)
Handle parameter name changes.- Parameters:
container
- The container for XML element.element
- The XML element name.attributeName
- The name of the attribute.attributeValue

filterEndElement
public void filterEndElement(NamedObj container, java.lang.String elementName, java.lang.StringBuffer currentCharData, java.lang.String xmlFile) throws java.lang.Exception
If the container is a property named "diffuseColor" contained by one of the GR actors, then check the format of its parameter to change it, if necessary, from matrix format to array format. Also fix the background color of ViewScreen3D. If the property name is "polygon" contained by an instance of PolyCylinder3D, perform a similar change from matrix to array.- Parameters:
container
- The object defined by the element that this is the end of.elementName
- The element name.currentCharData
- The character data, which appears only in the doc and configure elementsxmlFile
- The file currently being parsed.- Throws:
java.lang.Exception
- if there is a problem substituting in the new value.
-
toString
public java.lang.String toString()
