com.android.build.gradle.shrinker.RewriteOutputVisitor

public class RewriteOutputVisitor
extends org.objectweb.asm.ClassVisitor

ClassVisitor that skips class members which are not reachable. It also filters the list of implemented interfaces and rewrites generic signatures not to include references to "dropped" types. This is done by replacing the referenced type with java/lang/Object: the same as ProGuard does.
