Question

What is the difference between all of the .Net SDK class prefixes. I see

• On...
• IOnN...
• MRhino...
• IRhino...

Can someone please give me a brief rundown of what all these mean and what they might signify the class is used for?

Answer

The Rhino .NET SDK is a wrapper around the Rhino C++ SDK. For whatever reason, Microsoft choose not to implement the concept of const in the .NET framework. In C++, when modifying a data declaration, the const keyword specifies that the object or variable is not modifiable, or is constant. Thus, whenever you see a class name prefixed with an I, such as IRhinoObject, you will know that this is an object that cannot be modfied.
