com.google.gwt.dev.shell.rewrite.UseMirroredClasses

public class UseMirroredClasses
extends ClassVisitor

A general Class Visitor which will take any of the method calls in it's list and replace them with static calls to another method (the "mirrored" method) in another class (the "mirrored" class). This method should take the original object as it's first argument, followed by the rest of the arguments to the method. The "mirrored" class will not be rewritten, allowing the "mirrored" method to do whatever modifications are necessary before calling the original method (if desired). Methods which should be rewritten are listed in the mirroredMethods map below. Note that our mirroring process is not robust enough to rewrite methods on subtypes.

Description copied from class: ClassVisitor

Visits a method of the class. This method must return a new MethodVisitor instance (or null) each time it is called, i.e., it should not return a previously returned visitor.

Overrides:

visitMethod in class ClassVisitor

Parameters:

access - the method's access flags (see Opcodes). This parameter also indicates if the method is synthetic and/or deprecated.

name - the method's name.

desc - the method's descriptor (see Type).

signature - the method's signature. May be null if the method parameters, return type and exceptions do not use generic types.

exceptions - the internal names of the method's exception classes (see getInternalName). May be null.

Returns:

an object to visit the byte code of the method, or null if this class visitor is not interested in visiting the code of this method.
