soot.toolkits.scalar.LocalSplitter

public class LocalSplitter
extends BodyTransformer

A BodyTransformer that attemps to indentify and separate uses of a local variable that are independent of each other. Conceptually the inverse transform with respect to the LocalPacker transform. For example the code: for(int i; i < k; i++); for(int i; i < k; i++); would be transformed into: for(int i; i < k; i++); for(int j; j < k; j++);

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.
