Concerning linear complexity, what would be the references in the standard to back this up? I am unable to find any, which leads me to believe it could be implementation defined (one could imagine scenarios with primitive types where the behaviour need not be linear).
- It was defined linear in C++03 (Table 67 Sequence requirements in 23.1.1[lib.sequence.reqmts]/4 defines clear() in terms of erase(), and erase() has a complexity clause for vectors in 188.8.131.52[lib.vector.modifiers]/2 that states "Complexity: The destructor of T is called the number of times equal to the number of the elements erased"). In C++11, clear() is no longer defined in terms of erase() for sequence containers, we could make a note (this is LWG 2231) --Cubbi 19:05, 19 February 2013 (PST)
- That makes sense, as I was using the C++11 standard as reference. I think a note could be quite usefil. --Juanchopanza 09:46, 20 February 2013 (PST)
