internalTransform

protected void internalTransform(Body body,
                                 String phaseName,
                                 Map<String,String> options)

Description copied from class: BodyTransformer

This method is called to perform the transformation itself. It is declared abstract; subclasses must implement this method by making it the entry point to their actual Body transformation.

Specified by:

internalTransform in class BodyTransformer

Parameters:

body - the body on which to apply the transformation

phaseName - the phasename for this transform; not typically used by implementations.

options - the actual computed options; a combination of default options and Scene specified options.
