public class LocalPacker
extends BodyTransformer

A BodyTransformer that attemps to minimize the number of local variables used in Body by 'reusing' them when possible. Implemented as a singleton. For example the code: for(int i; i < k; i++); for(int j; j < k; j++); would be transformed into: for(int i; i < k; i++); for(int i; i < k; i++); assuming to further conflicting uses of i and j. Note: LocalSplitter is corresponds to the inverse transformation.

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
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.
