Thread-safe vector: Is this implementation thread-safe?

Question

I have a question regarding the term thread-safety. Let me give an example:

#include 
#include 

/// A thread-safe vector
class Th         


        

Answer 1

Yes, I would. Both public methods are protected by locks, and all the special member functions (copy/move constructor/assignment) are implicitly deleted because std::mutex is neither copyable nor movable.
