public interface ContextClassTransformer

This is similar to a ClassFileTransformer, but it takes additional arguments containing some context about the current class transformation including the class match results paired to this transformer. These transformers are added by calling: InstrumentationContextManager.addContextClassTransformer(ClassMatchVisitorFactory, ContextClassTransformer).
