I have here a class called ClassMaker whose greeter method returns an
instance of anonymous class containing a hello method:
I would like the anonymous class’s hello method to access whatever the
value of my ClassMaker instance’s @howdy ivar may be at the moment
greeter is called. I am presently doing this, as you can see, by giving
the anonymous class an initialize method and passing the @howdy ivar’s
value into an ivar of the anonymous class’s instance.
This works but seems heavy-handed. I feel I should be able to do it
without the anonymous class having any initialize method at all. The
whole situation has “closure” written all over it. So I tried to define
the hello method to accomplish the same thing using evals and blocks and
other tricky stuff, and became hopelessly confused. Could someone
straighten me out? Thx - m.
