Practical Application of Adapter Method

This week I chose to write about the adapter method because it is a great tool to have when working with incompatible interfaces and will help me in the future by creating more of an understanding about different types of frameworks. Since we are learning about 3 different design patterns, I figured adapter would be an interesting topic because can be compared to the porting of programs or video games to different types of hardware/ interfaces. Let’s first start off by talking about what the Adapter Pattern is. The adapter pattern works to allow two incompatible interfaces either work together or use attributes of one another. One example is a memory card reader in a laptop. When a memory card is plugged into the card reader so that the laptop can interpret the data. This article talks about how media devices can be adapted to play different formats.

This article explains the difficulties of porting or adapting a video game to other platforms because of the middle-ware or libraries that need to be used. For example, let’s say one game is built for a PC, however down the road the developers would like to adapt it to work on mobile phones or tablets. One struggle of this is that some developer tools are often built with closed sourced tools. This means that the game would need to be rebuilt from the ground-up because the libraries and tools needed are locked. Some game development tools are aware of this and actually include tools to directly adapt the libraries from one platform for another. Some optimization is still necessary by the developer, however it makes it so that these games and programs can run across multiple platforms. The reason I believe developers would want to make their products available across multiple platforms is because they want to maximize profits by adding more groups of users to their potentially interest list.

Performance is also an issue, sometimes it is more than code that can hinder the game. The actual hardware can greatly impact an adaptation of the game due to the fact of how it was built for another hardware architecture. The article says “The number one showstopper in game porting is the usage of closed-source tools, engines or libraries. Game developers should be aware of the technical decisions they are making, and how they will later affect portability of their game.”. This can create great issues and slow down for development time, especially if a deadline needs to be met.

One more important take from the article is language choice. From the article, “Is it going to properly compile in all platforms? Will it perform well? Beware of “too new” languages with super features (for example C++11) that might not be completely supported in all platforms (as we have painfully realized).” As we can see, there are many factors in adaptation of different types of software, and if we can create our programs with future adaptations in mind, adapter implementation can be organized in such a way to make the process easier.
