These are the disgn patterns I'm going to study

Abstract factory
Adapter
Composite
Decorator
Factory method
Observer
Strategy
Template

I'm using the book "Design Patterns: Elements of Reusable Object-Oriented Software" by Erich Gamma, Richard Helm, Ralph Johnson, and John Vlissides

heya rick
there is nothing on the decorator not Template Patterns in the textbook, so unless they're synonymous with something from the text book you can probably leave em out

you left out one of the most important ones (IMO) Visitor pattern, its refered to twice in the textbook and i think its is important to know because of its dealing with files, directories etc,
heres 13 patterns i extracted from the textbook:


1. Visitor p184 ---> i reckon important
2. Composite p196
3. Observer (Publish-subscribe) p196
4. Serializer p227 ---> i reckon this ones quite important too ?
5. Monostate p242
6. Command p262
7. MetaObject (Reflection) p344 ---> i reckon quite important too
8. AbstractFactory p360 ---> i reckon mega important
9. Singleton p361
10. Facade p381
11. Adaptor(Wrapper) p386
12. Strategy p396
13. ModelView p391 ---> most mega important


Actualy now that ilook at it most seem important, so i've just noted the ones i reckon we will defs be tested on, ModelView for sure because thats what all the UML style moves towards progressively in the textbook

Oh ja and the book MENTIONS the Iterator pattern in the same heading of the section of visitor but doesn't bother to define it so that ones out i'm sure

hmm. I think your list is better than mine, Iva. I'll knuckle down on those

ok, people should probably use other resources (that pdf is brilliant) for getting an understanding of the patterns though as the text book is hopeless

I also reckon that UML designs are going to feature in the exam quite a bit seeing as there isn't enough time to test big programs that use the design patterns. They can test for design pattern understanding by making us do a design...thats my prediction

Cheers! I'm in a generous mood, so if anyone wants that pdf, drop me a mail at

rick.softly at gmail dot com.

I have it parked on a site.

The latest tut letter says we can omit chapter 17, so I guess model view is not examinable.

shot ! thats some wasted time saved!

I'd like that pdf please kilhra@gmail.com

I've sarted on my own summary of the design patterns and I thought that maybe we could start a thread where people say how they understand the patterns and also what applications there are for them.
I'm not sure I understand all of them, and I thought that this would be a good way to help those of us that don't understand and also give us a broad range of possible applications

id like that pdf please jkoorts@gmail.com

I think that's a great idea, Kilhra. After all, that's what a forum is for. I'm busy nailing down some 340 basics atm, but i would also like to post ideas for commentary.

omg! now we have to study chapter 17! aargh

what? where do they say that?

I'm putting money down we'll get something on threads and thread safety, as in the field you have to use that a lot.
