public class CastAndReturnInliner
extends BodyTransformer

Transformers that inlines returns that cast and return an object. We take a = .. goto l0; l0: b = (B) a; return b; and transform it into a = .. return a; This makes it easier for the local splitter to split distinct uses of the same variable. Imagine that "a" can come from different parts of the code and have different types. To be able to find a valid typing at all, we must break apart the uses of "a".

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.
