MemberRemover (ProGuardCORE)

java.lang.Object

proguard.classfile.editor.MemberRemover

All Implemented Interfaces:: ClassVisitor, MemberVisitor

public class MemberRemover extends Object implements ClassVisitor, MemberVisitor

This visitor removes all members it visits in a ProgramClass.

It should be used in two steps:

In the first step, the collection step, all program members to be removed should be visited.
In the second step, the removal step, the program class containing the program members should be visited. This will actually delete all collected members.

For example, to remove all fields in a program class:

     MemberRemover remover = new MemberRemover();
     programClass.fieldsAccept(remover);
     programClass.accept(remover);
