You can capture the call to B::method_b() with 'call("% 
B::method_b()")'. The intersection of these join points with all join 
points within the class A give you all calls to method_b inside class A:

call("% B::method_b()") && within("A")

This is, of coarse, not what you wanted, but describes the idea. 
Selecting all join point within method_a() is not yet implemented in 
ac++. However, future releases will support this with the same syntax:

call("% B::method_b()") && within("% A::method_a()")  <-- not yet!

I hope that the first pointcut shown here is already sufficient for you. 
If not, tell me.

Yours,

Olaf
