Let the name of the "embedded class" (which is not embedded at all in your 
example code) be E.  You could either store the information in the E 
instance upon or after construction, or you could pass a reference to the A 
instance to the E instance’s method, so that you can call the A instance’s 
public methods from the E instance’s methods.

But consider the Law of Demeter.

It would simply be wrong.  Monty (Python) is (literally) a group of Actors.
