I have an instance
target being a member in an instance (owned by)
o of class O. An instance
u of class .U. should be able to express desire to make
o change the state of
target but not directly, so through an instance
ui of class UI. Can someone give me an example of some
Java class having code doing this in a nice way or maybe name the
pattern I am close to here ? Might be time to get a book on design patterns
