For this, I need an interface and maybe a container for resolving my instances. But how you do this in C++? In the same way. The difference is that where you “program to an interface” in C#, you “program to a base class” in C++. Additionally, you have extra tools in C++ that you do … Read more

I don’t actually think that DI/IoC are that uncommon in Python. What is uncommon, however, are DI/IoC frameworks/containers. Think about it: what does a DI container do? It allows you to wire together independent components into a complete application … … at runtime. We have names for “wiring together” and “at runtime”: scripting dynamic So, a DI container is nothing … Read more

A JavaBean is just a standard All properties are private (use getters/setters) A public no-argument constructor Implements Serializable. That’s it. It’s just a convention. Lots of libraries depend on it though. With respect to Serializable, from the API documentation: Serializability of a class is enabled by the class implementing the java.io.Serializable interface. Classes that do not implement this interface will not … Read more
The Inversion of Control (IoC) and Dependency Injection (DI) patterns are all about removing dependencies from your code. For example, say your application has a text editor component and you want to provide spell checking. Your standard code would look something like this: What we’ve done here creates a dependency between the TextEditor and the … Read more
