The first two look like moving a chunk of code. The last one isn’t quite so clear, but I think you’re saying that you are calling a function that includes that moved code.

The reason why it isn’t clear to me is that the blue arrow makes it look like code was moved AND then has to serve double-duty being “and now you are calling this function”.

But then, that assumes I’m right, and I think I might not be.

My guess? Extract Method

(Step 1) I take it that the blue line is a set of procedural code we wish to refactor, and the solid straight lines are the code we’re interested in.

(Step 2) We perform an extract-method refactoring, hence the line at the bottom of the procedure producing separation.

(Step 3) This is where you sort of lose me. The picture syntax is reminiscent of UML, but I think it’s supposed to be a function pointer? Perhaps a different arrow would remove that confusion?

I also like that you don’t use real code in the illustration. The concept is easier to pick up when you keep the diagrams as simple as possible. That is assuming I got the message at all :).

Is the third step supposed to be Extract Interface?

1 to 2. Extract method from a huge method.

2 to 3. No idea. Null Object came to mind, but that doesn’t make much sense without more context.

Extract method and strategy pattern?

D’oh, that third step is meant to be inheritance (glad I checked).

So step 1: lines are causing a problem or I am interested. Step 2: extract into a method and then invoke the method.

Step 3: subclass and override the method to do nothing.

Looks like Extract Class followed with implement interface in it’s place. Still not 100% – at first blush I was more aligned with the other comments (Extract Method).

As for using more pictures – I’m a big fan of saying more with less. I’m sure a verbal description will no doubt fill in any “holes”, leaving the students with pictures to remind them of the concepts that were being discussed.

Extracting a chunk of code and then inheriting the subject made me think of “replace type code with inheritance”.

When you think about it though, a lot of refactorings would look very similar when drawn this way.

The first two are Extract Method, the third can only be an inheritance. The Phi suggests that the extracted method is overridden with an empty implementation.

it must be a decorator pattern using class itself. decorate(me).extractedMethod

- Extract method also for the step2.

- “Mock by inheritance” for step3 ? (if the inherited class is used for testing).

I haven’t read Michael Feather book, but this particular refactoring is discussed in his 2002 Paper (Working Effectively with Legacy Code) as an example of “Breaking Internal Dependencies”. Maybe this name (BID) could be used ?

It would have been clearer to me, if the blue arrow in the last diagram was from the black lines to the subclass or even better if it was omitted all together. The common color (black) of the extracted method and the overridden method in the subclass are probably enough. The blue arrow is just distracting and not contributing.

If it wasn’t for the blue arrows, I would not have understood the meaning of both steps (“extract method” and “decoupling from the method implementation by introducing interface”) – i.e. though to say “if I understood at all” ... ;-)

Looks like extract method and null object to me. I do quite like the style of picture.

I like the style and also the “Extract Method” was immediately understandable. The problem with the third figure is, that it is not clear what the box represents. Symbol “black box with thin black line” is used for a method and a class at the same time. I think you have to come up with a symbol for a class (black box) that has methods in it (...containing blue boxes for every method)—just as an example.

I would call the full sequence: “Extract and Inhibit”.

1/ We would like to be able to switch on and off a part of a processing 2/ “Extract Method” or “Introduce Template Method” 3/ Override with do nothing method

Separate a concern to its own class. Step 1: identify a concern. Step 2: move to a separate method. Step 3: move to a new class.

I love this diagram and I think using doodles to represent refactorings has a GREAT potential.

Looks like Extract Method, followed by Push Method Down???? Can’t really tell on the last one.

1. Move your conclusion statement from next to the thesis statement to the last paragraph. 2. Discard the excess sentences.

(I have not read the other comments yet.)

The thing that threw me was the source of the blue arrow in the third photo. What was being dragged from the original location of the method into the derived class? I didn’t get visually that it was stubbing the method.

Maybe if the arrow had gone from the extracted method to the null….?

Just to throw my hat into the ring: I’m going with Extract Method followed by introduction of a Template Method.

As other commenters have mentioned above this reply, however, the blue arrow and the ‘0’ could do with some clarification lest they cause misinterpretation.

Since this is TDD, my guess is the to mock out the dependency by 1. first extract method, 2. provide stub by inheritance …

Regarding your second question: I think build-up is more effective when illustrating a sequence. I think the diagrams are quite good, though the last step had me scratching my head a little with the theta or zero or whatever.

In a slide show it can all be one slide that you toggle through as you talk to expose the next step. For a hand-out it’s good to have keynotes describing each step in the sequence.

In the first box: you notice a piece of code that prevents you to put the class under test.

In the second box: you extract it to a method. even if done manually, which is a pretty safe step.

In the third box: by providing an empty stub, you effectively remove the dependency and rest of the code can be put under test.

Apparently, by introducing a specialization you are able to remove a method, so I’d say it could be e.g. “Replace Conditional with Polymorphism”

• Some people asked about the triangle – I took that from (among other notations) UML. It does represent inheritance.
• Probably need some kind of iconic representation of method and class – making it clear that the black lines in the second diagram are an extracted method in the current class.
• The circle with a zero was confusing – I meant it to b an empty method.
• The blue line confused some people. I’m going to keep that in (or some version of it).

While it was somewhat clear without text, it was also somewhat confusing.

I’m going to make several changes and post the results. One big change is I will show the original black lines with some kind of external dependency, which will then move into the extracted method, and then will disappear in the derived class.

Thank you all for your guessing and feedback.

I also prefer the diagrams as a sequence rather than all together (as in the next blog post). There was a comment on that as well.

Looks like Extract Method

yes fine very method

The monster beats headphons are semi-open in design

However, the headphone industry is greeted with far less unanimity. dr dre headphons targeted toward audiophiles are often considered weak or thin sounding by the general consumer. Despite a price tag worth more than 5 times the amount of the monster beats dre studio headphones they are used to, the consumer may not be inclined to agree with the more expensive headphone’s proclaimed superiority. In order to please both the consumer and audiophile demographics, headphone companies must either exhaust their R&D departments and often come up short, discover some magic voodoo potion, or simply give up! I know for certain that in the case of the Beats By Dr Dre Solo, V-Moda did not subscribe to the latter.The beats headphons headphones themselves are semi-open in design and allow sound to leak into the outside. For this reason, the Beats By Dr Dre may not be the ideal headphone choice for some listening environments.

Some may inquire as to why Beyerdynamic would choose to create an open-back headphone. The reason as specified by many manufacturers that design open-back New Style Beats By Dr Dre headphones is that it is easie.House of Marley has consistently surprised us with their uniquely designed monster beats dre studio headphones. The House of Marley Trenchtown Rock Destiny is their latest offering, a noise cancelling headphone which competes with many similarly-priced noise cancelling monster beats dre studio headphones and ‘rapper monster beats dre studio headphones’. Overall I felt that the Destiny is a good choice for a listener who likes great style, active noise cancellation and up-front forward bass.The noise-cancelling ability of these cheap beats by dre studio headphones is pretty good, however there may be better options at this price point if Active Noise Cancellation is more important to you than the aesthetics of the cans. I do however have two quibbles with regard to the way the feature is implemented. One is that in order to hear music, you must use the noise cancelling feature.

This means that your batteries better not run out, or you should be prepared with extra batteries (two triple A). While it is not uncommon for noise cancelling Beats By Dr Dre Pro to require the noise cancelling feature to be activated in order to hear music, several new models are coming out that will still output sound when batteries are dead, or noise cancelling is in passive mode. The second is the louder than average thump sound which one hears when switching the noise cancellation on while the monster beats dre studio headphones are on the head.Listening to Maroon Five’s “Moves Like Jagger” I was very impressed with the immersive quality this headphone had. If you want a headphone that makes you dance, these Destiny monster beats dre studio headphones may very well be your destiny.With regard to accessories, beats dre studio do not offer much. The cable itself is built into the headphone (Y-split style) and is not user replaceable. The cable itself is very sturdy, extra thick and may benefit from a Beats By Dr Dre Solo headphone extension cable if one is going to be more than 4 feet from their source.
