This question indirectly relates to design patterns, but is at a lower level of design that I thought might be appropriate for this group. In this problem...
Brian: I am a little confused here. It sounds like you have one method in the interface: doAction( action) Does the calling routine not know the action it is...
Sorry to confuse you on this, but I will try to clear things up here. I didn't mention the whole problem because it's a bit lengthy and I thought I could just...
Brian: That adds some other pieces of information. The thing is, patterns are really about relationships between classes. In this case, there is the question...
OK, we'll be studying the bridge pattern this month. To get us started, everyone should read the bridge chapter of my book. You can get this on-line at ...
Neil asked: I was wondering what the status is of the discussion of the Bridge pattern? I'll be writing up something on the bridge and posting it later this...
I'm new to Design Patterns.... It would help me immensely if other Bridge pattern scenarios besides the one in your book could be discussed - with or without...
Neill: I will be posting more later today, but the way to "identify" a bridge is needed is when you have a group of related objects (i.e., they all derive from...
Hi, all, I will start with bridge later. But now I have a real world problem regarding creational patterns. Can someone give me some hints? BTW, it is a great...
Thanks for your comments on the book. Regarding your problem. First, you do have a factory problem, but it isn't an abstract factory. An abstract factory is...
I have uploaded an example of the bridge pattern. It is in C++ (we're doing a Java example within another week or so). Check out the files section to get it. ...
Thank you for the response. That is a very nice and very helpful response, by the way. My message is really long this time. But the most frustrating questions...
This e-mail helps clarify things. THis is a good dialog I hope others are following. You are experiencing a common misconception many people have when they...
Now I think it is no harm to put instantiation code in constructor. But the problem remains. Let me explain it by comparing the two approaches with Java code: ...
I was asked this question off-line, but was given permission to use it so I am posting it here. This was in reference to the free seminar I am doing January...
I would say that what you've described is accurate, but only partly so. They are examples of coupling and cohesion - not the whole story. Here is some...
... like ... other ... relations ... McConnell's ... Thanks for the reply, I read McConnell again and the different flavors of cohesion and coupling. I think I...
Art: Great. And thanks for the examples. McConnel's book is an interesting example of how these concepts have been around a long time. OO doesn't really...
I like the name changes. I don't see that you need more than one type of book. Simply instantiate the appropriate factory and then use that to get the books...

Hi, I have recently joined this group and am highly impressed with the subject matter / content. I am reasonably new to OO, and Pattern usage. My first...

Tony: From what I gather, I don't see anything wrong with what you've done. A way to see if the design is solid is to look if there is any duplication in the...
