Given a C API to a library controlling sessions that owns items, what is the best design to encapsulate the C API into RAII C++ classes? The C API looks like: HANDLE OpenSession(STRING sessionID); void CloseSession(HANDLE hSession); HANDLE OpenItem(HANDLE hSession, STRING itemID); void CloseItem(HANDLE hItem); Plus other functions th...

Hi guys, currently I am thinking about data encapsulation in C# and I am a little bit confused. Years ago, when I started to learn programing with C++, my professor told me: - "Create a class and hide it data members, so it can't be manipulated directly from outside" Example: You are parsing an XML file and store the parsed data into ...
I would like to know in what scenarios you use encapsulation. The purpose of this question is collaborative. So feel free to share your own experience when the subject is encapsulation. Some scenarios: Calculated property public class Order { private List<ListItem> listItems = new ArrayList<ListItem>(); public double getTota...
In visual studio you can set accessors by using the encapsulate field refactoring operation on a declaration (Ctrl + E,R shortcut). Is it possible to generate (using the default settings) the accessors of several field at once ? Having : private int one; private int two; //etc and generating : public int One { get { return one;...

How can i perform dependency injection without breaking encapsulation? Using a Dependency Injection example from Wikipedia: public Car { public float getSpeed(); } Note: Other methods and properties (e.g. PushBrake(), PushGas(), SetWheelPosition() ) omitted for clarity This works well; you don't know how my object implem...

Does Encapsulation is information Hiding or it leads to information hiding?? As we say that Encapsulation binds data and functions in a single entity thus it provides us control over data flow and we can access the data of an entity only through some well defined functions. So when we say that Encapsulation leads to abstraction or infor...
