First off–”Bill” is fine. We’re not fancy on this blog. As for what design pattern to use on your project, just ask yourself, “What would I like to change, add or enhance in a possible update?” If you want to change the interface to an object; then go ahead with the Adapter pattern. What is the “method in which the user obtains the image”? If the focus is on changing the method, do you mean the operations in the method (algorithms). If so; then look to a Strategy pattern. If you have something else in mind; then take a look at the ‘Magic Table’ and see what variation most closely matches what you want to be able to change.

Kindest regards,
Bill

I agree with you, I wish that Design Patterns were easy. I find myself in a constant struggle to figure out the best way to go about planning a project, architecture wise, and in some regards which Patterns to use and when to use them.

I think that with time I will be better able to figure this out, and with such a great recourse as this site has become, I know that I will find more then one answer right here on this blog.

The project that I mentioned before, is an online application. The app allows users to take a photo with their webcam, or upload an image to use, they are then able to adjust and rotate the image. I was considering going with an Adapter pattern for getting the users image. I thought it would be a good approach since to provide users with the same methods to (capture – upload bitmapData to server) the image, and Encapsulating what varies, that being the method in which the user obtains the image (webcam and uploading).

What is your opinion? I would love to hear what you think would be the best approach to using good OO practices.

Looking forward to hearing from you once again.

Chandima and I are glad you like our blog and book. We enjoy what we’re doing and don’t mind putting in the time. In many ways I wish that Design Patterns were easier, but in time everyone comes to understand and use them to make their work better and eventually easier.

Kindest regards,
Bill

Up until this point, I have been a quiet reader of your incredible blog. I have read Actionscript 3 Design Patterns over and over again in hopes of one day being able to even consider myself in the same arena as you are. One day I hope to get there.

After reading today’s post, I thought it was time for me to speak for the first time, this post really hit home with me.

I am currently about to embark on phase 2 of a project that I started several months ago. I had a tight time-line, and I feel like, had I had more time, I would have built it differently.

I am now faced with phase II of this project. I wish I had taken into consideration the additions that would have come up functionality wise as you did with your Video player example.

Thank you very much for all your hard work, I am amazed how much you are able to do, at what seems like at the same time, and do it at such a high level. You are both a role model and an inspiration to me. Thank you!
