Welcome back for another episode in the pattern series! This will also be the last article about Design Patterns, since I've finished reading the Head First Design Patterns book :) It's been a very interesting journey, lots of new patterns learned , lots of knowledge gained , and now it's time to apply...

It's been a while again, but it's time for another pattern. Today we'll look at the State Pattern . First of all, the definition: " Allow an object to alter its behavior when its internal state changes. The object will appear to change its class. " Read more at http://blog.cumps.be/design-patterns-state...

It's been a little while again. I blame myself for installing World Of Warcraft again, too addictive. Anyway, time for the Composite Pattern . This is one I'm having a little trouble with to describe clearly. Let's start with the definition: " Compose objects into tree structures to represent part-whole...

Time for the next part in our series , the Iterator Pattern . Let's start with the definition: " Provide a way to access the elements of an aggregate object sequentially without exposing its underlying representation. " Read more at http://blog.cumps.be/design-patterns-iterator-pattern/

Time for yet another pattern, the Template Method Pattern . Have a look at all the other patterns in the series as well. The definition: " Define the skeleton of an algorithm in an operation, deferring some steps to subclasses. Template Method lets subclasses redefine certain steps of an algorithm without...

Time for another, simple , design pattern. The Facade Pattern . I'm going to need a break soon, getting a bit burned out, which never is a good thing. Anyway, the definition of today's pattern: " Provide a unified interface to a set of interfaces in a subsystem. Facade defines a higher-level interface...

We've seen quite a few patterns so far, and I'm glad so many people like them. They turned out to be the most popular posts I've ever written when it comes to development. Thanks! :) A little overview for the late joiners: Long Absence - Design Patterns Design Patterns - Strategy Pattern Design Patterns...

What's a lonely geek to do late in the evening? Write about the Command Pattern of course... Let's start with the definition: " Encapsulate a request as an object, thereby letting you parameterize clients with different requests, queue or log requests, and support undo-able operations. " Read more at...

A little follow up from yesterday's Singleton Pattern , where I asked for some help on how you would approach a generic singleton . With the help of Andrew Stevenson and ExNihilo , we came up with the following Generic Singleton Pattern : Read more at http://blog.cumps.be/design-patterns-generic-singleton...

Today we'll have a look at a well known pattern, the Singleton Pattern . Most people have already heard about this one. The definition: " Ensure a class has only one instance and provide a global point of access to it. " Read more at http://blog.cumps.be/design-patterns-singleton-pattern/
