As part of my research, I am looking for statisitcs on the use of several language features. I'd be grateful for any references (esp. published papers), containing recent results.
Primarily I am looking for:
* The use of inheritance (depth of hirarchies, number of childer, number of parents (MI) etc.)
Programming languages: Any OOP lang. Esp. C++, Ada, Java
* Use of "reflection" in Java systems (% of systems that use it; what kinds of uses)
* Breakdown of casts in C++ code (according to the modern classification: dynamic_cast, const_cast etc.)
Thanks in advance,
