Class ImplicitUpcastAnalyzer

java.lang.Object

com.google.gwt.dev.jjs.ast.JVisitor

com.google.gwt.dev.jjs.impl.ImplicitUpcastAnalyzer

public class ImplicitUpcastAnalyzer
extends JVisitor

This class will identify instances of an implicit upcast between non-primitive types, and call the overridable processImplicitUpcast method. TODO(jbrosenberg): Consider extending to handle implicit upcasts between primitive types. This is not as straightforward as for reference types, because primitives can be boxed and unboxed implicitly as well.
