Re: Java Accessors Are They Evil?

Wow, I feel like I've been doing it all wrong now. I am starting to see what
you are saying though. I just need to play with it a bit I guess.

Do you know of any good articles or books that explain this kind of pattern?
I was looking last night, but wasn't sure what to look for. I did see plenty
of examples with getters and setters though.

Thanks,

Think of passing the Address object a context on which to write the
address. The context object would have methods that accept address
lines. The Address object would know how to write lines to an interface
implemented by the context object. So the method might be
Address.writeOn(DisplayInterface context).

First off I would thank you all for taking the time to read the article.

It looks like I've got some re-training to do in my mind. I think I
understand the concept that is happening now, but I need to figure out
how this all works in an application.

I have an application that get's customer data from a database and then
writes it to an XML file so I can process it with the GoogleMaps API.

I am currently building a list of customers and passing it the class
that creates the XML. This class uses a method getShipToAddress() which
returns an Address, but the Address class has getters for address lines,
city, state, etc. So I'm trying to figure out how you show that.

I guess, which I know is talked about a bit in the article, I don't
understand how you can use an object for a UI without at least read-only
accessors.

I guess it's back to the drawing board.
