TDDB84 Design Patterns
The course literature consists of online resources and scientific papers, as well as a reference textbook on Design Patterns:
Below is a list literature you can read in order to prepare for the seminars. During the course you might also need to search for additional information on your own. For this you could use the online search engines of LiU , Google Scholar or other search tools for scientific papers that you are familiar with.
Exam seminars have a number of required reading material that you need to read in order to prepare for the seminar. In the list below this material is marked in red text. For lab seminars the only requirement is that you have done the labs.
Understanding design patterns
No required reading material
Mainly the course book, see above.

Design patterns and software qualities
SOLID is an acronym for a set of design principles in object-oriented design of software. The Wikipedia description of SOLID is good, but you might also need to find examples of violations of these principles, in order to understand how they are to be applied.
- Example of a violation of the Open-Closed Principle
- Example of a violation of Liskov's Substition Principle
Justification for design:
- Software Quality , definitions and metrics.

Some design patterns in different languages. For example Proxy:
In Java, most often implemented dynamically using an
InvocationHandleror a third-party class generation package such as CGLIB .
- In C#, proxies can be created as dynamic objects using the class DynamicObject , or using a third-party class generation package such as Castle Project .
In Ruby, you typically catch method calls to non-existing methods
method_missingto create a Proxy.
- In Objective-C, forwarding unknown messages (method calls) is used to create dynamic proxies.
- In Common Lisp, you can define a custom dispatch mechanism for methods that are are proxy methods by using the Meta-Object Protocol to declare that they are a special kind of methods, which means that they can be made into proxy methods.

Some design patterns are implemented using more or less standardized components or techniques. Here is a list to external resources for some of them. More references are in the lecture material and will be moved here for easier reference.
Abstract Factory, implemented using Dependency Injection (Inversion of
- In Java Enterprise Edition, Dependency Injection is part of the standard as CDI
- In Java, there are also third-party dependency injection frameworks such as Spring
- The Open Source frameworkNinject in .Net (C#/VB)
- The Open Source framework StructureMap in .Net (C#/VB).
- The Open Source framework Castle Project in .Net (C#/VB).
- Microsoft's DI framework Unity in .Net (C#/VB)
- In Java, all classes in the standard library called something with Listener are typically observers. To implement your very own, with no no connection to existing event sources, you would probably start with the class Observable
- In C#, you typically observe events in sequences of items, and implement IObservable
Below you will find topics which might not nessacarily concern a specific seminar.
Critique and reflections
These are some of the critiques usually found against the (over-)use of design patterns in software.
- On the use of an Inversion of Control (IoC) container for Dependency Injection in Spring , an application framework for Java.
- On the harmful effects of using the Singleton pattern .
- On the underspecified Visitor pattern .
- On the difficult-to-understand-and-debug Template Method design pattern .
- On the absence of Design patterns in dynamic languages, Peter Norvig. Object World 1996.
- Critique against Dependency Injection when using open languages like Ruby
