public class DexTrapStackFixer
extends BodyTransformer

Transformer to ensure that all exception handlers pull the exception object. In other words, if an exception handler must always have a unit like $r10 = @caughtexception This is especially important if the dex code is later to be translated into Java bytecode. If no one ever accesses the exception object, it will reside on the stack forever, potentially leading to mismatching stack heights.

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:

b - 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.
