Class InvocationWeaver

java.lang.Object
com.googlecode.d2j.tools.jar.BaseWeaver
com.googlecode.d2j.tools.jar.InvocationWeaver
All Implemented Interfaces:
org.objectweb.asm.Opcodes
public class InvocationWeaver extends BaseWeaver implements org.objectweb.asm.Opcodes
1. Replace class A by another class B, include superclass, new for 

     class Test1 extends A ...
     class Test2 implements A ...
     void amethod(A a) ...

after 

     class Test1 extends B ...
     class Test2 extends B ...
     void amethod(B a) ...

2. Replace method A to another method B, method B must be public static, and in either 'public static RET b(ARGs)' or 'public RET b(Invocation inv)' RET: same return type with method A or Object ARGs: if method A is static, ARGs is same with method A, if method A is non-static the ARGs is 'thiz, arguments in methodA' 

 public int a() {
     Test t = new Test();
     return t.test(1, 2);
 }

after 

     // direct replace
     public int a(){
         Test t=new Test();
         return B(t,1,2);
     }
     // or by MethodInvocation
     public int a(){
         Test t=new Test();
         return test_$$$_A_(t,1,2)
     }
     // the replaced invoke method
     public static int test$$$_A_(Test t, int a, int b){
         MethodInvocation i=new MethodInvocation(t, new Object[]{a.b})
         return B(i).intValue();
     }
     // the callback if MethodInvocation.proceed() is invoked
     public static Object test$$$$_callback(Test t, Object[]args) {
        return box(t.test(args[0].intValue(),args[1].intValue()));
     }

3. Replace Methods Implementations 

 public int test() {
         ...
 }

after 

     public int test(){
          MethodInvocation i=new MethodInvocation(t, new Object[]{a.b})
          return B(i).intValue();
     }
     public int org_test(){
         ...
     }
