Unity interception mechanism does not work between methods inside same class

I´m working with C# + Unity (2.1). Intercepting methods works fine if a call comes from outside, but between methods inside the same class only the first method is intercepted. For example:

    [InterceptorAttribute]
    public int A(int a, int b)
    {
         return B(a, b);
    }

    [InterceptorAttribute]
    public int B(int a, int b)
    {
         return a+b;
    }

The call to method B() is not intercepted. Can anyone help?

If you look at how interception is implemented, it becomes clear as to why this happens. An interceptor is basically a proxy that wraps around the original object and forwards calls to it, in addition to calling any associated handlers:

public int A(int a, int b)
{
  callHandlers();
  return originalObject.A(a, b);
}

public int B(int a, int b)
{
  callHandlers();
  return originalObject.B(a, b);
}

Even though the two calls are individually intercepted, once originalMethod.A is invoked, the call to B will only invoke originalObject.B, not proxy.B.

Perhaps if you explain what you're using interception for, there may be a better solution to what you're trying to do.
