What are the differences between the new technology called native client from google compared to existing technologies like Java from Sun and.

The only benefit I figured out is performance. And this will be plattform dependend, right? This is really annoying. So look here for the workaround. Normally the reason why I write blogs is to inform other people about interesting things I found or I am thinking about. One of my latest posts was about the spring rich client. Because of this project and picocontainer I read a lot about design patterns. The most obvious design pattern in spring is called dependency injection. This design pattern helps the software architect to loosly couple components.

It could work like follows just for the JSE-developers under us:. MyInterface could be a class as well. You will get back an instance of class ClassAwhere objectA is not null! The dependency was defined by the method setMyInterface — this is called setter injection. Other kinds of injections are:. Where picocontainer campaigns for constructor and spring for setter injection but both projects offer at least the mentioned kinds of injection. It is correct that you can create your own small framework or even set up the objecs by hand to achieve the same: But I guess you are lazy and will choose one of the open source frameworks.

Now, all is explained to understand my 3 questions. Hopefully someone out there will have an answer! You want to sell a nice designed, but complex library. The library offers a lot of functionality and you want to split it into opeenbook coupled components.

So, if you use e. Should I really use dependency injection here? Or should I use a dynamic service locator instead; to decouple my components within the library? The point here is that to do testing, you need to easily replace real service implementations with stubs or mocks.


However there is really no difference here between dependency injection and service locator: In these cases even a minimal assumption about a Service Locator is a problem.

What would you do? Would you use a service locator or dependency injection inside the library? I stumbled over this question while I used picocontainer. They say you have to avoid singletons, because it is difficult to test and to replace. Imagine the following singleton:.

Now it is really easy to replace the implementation of the Logger interface e. But in picocontainer you have to set-up the configuration for the wiring of the classes by yourself e. That means you could specify the implementations of the interface by:. To let picocontainer call the default constructor. But please, this is just a draft. Maybe this wikipedia article is a better place for you.

And please correct me, if I posted oprnbook or invalid facts about C. Or if you missed a great feature of C or an example of the facts, then please let me know.

In c we have real generics, with separate namespace: For a direct comparison of these two packages, please visit this page openbiok galileo computing and go to the chapter 7. Karussell Thoughts about Java and more. Today I need your help! Or is this only a marketing gag? If you are new to C it is a little bit different as in Java to create a test case. You can do the following Install NUnit Create a galioeo project with your sources.

Now you can set breakpoints and evaluate expression in the test class like you would do in HelloWorld. It could work like follows just for the JSE-developers under us: Other kinds of injections are: How should I design a library?

And this leads me to the next important question: Why is a singleton an antipattern? Imagine the following singleton: How can I avoid making all classes public? That means you could specify the implementations of the interface by: Whats cc# with my use case and my conclusion? NET languages are galiloe to each other. I know that there are now some more languages for the jvm, but the jvm was published with only one language: ToInt32 obj ; for enums only byte, short, long and int are valid no string!


Where we write in Java: Galikeo ref intVar ; or define a method by: Please see this doc. All the objects you define inside a. C protected internal — think of this one as the union of protected and internal, as the item is is modifying is either protected or internal. This item openblok be accessed from the entire assembly, or within objects which derive from this class.

SuperClassA constructor chain in c: TestMethod results in calling ClassA. Collections For a direct comparison of these two packages, please visit this page of galileo computing and go to the chapter 7. Only Array allows arrays that are not zero-based. Sort an array via: Adapter array ; class Sorter: Sort new Sorter galilel C has the keyword yieldwhich is useable if you implement IEnumerable.

In Java there is similar class BitSet.

IDE add an existing project to the explorer: You can drop it down and this will result in two views horizontal splitted editors of the current source file!

I know there is Mono, but when was the last time you tried to run the Visual Studio on Mono? And then look at Java: Eclipse, NetBeans, etc — all will run at least on linux and windows! Although I love Java there are really cool things in C: XmlSerializer linq it is possible to overload operators you can use string in switch statements!

Feel free to post your experiences with C!
