public class DexIfTransformer
extends AbstractNullTransformer

BodyTransformer to find and change definition of locals used within an if which contains a condition involving two locals ( and not only one local as in DexNullTransformer). It this case, if any of the two locals leads to an object being def or used, all the appropriate defs of the two locals are updated to reflect the use of objects (i.e: 0s are replaced by nulls).

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.
