Even the best require a special syntax for constructing objects (uncomplicated to examine at compile time) and/or cooperation from derived class authors (unachievable to check at compile time).
No. dyn_array will not be resizable, and it is a secure strategy to refer to a heap-allocated mounted-sizing array. Not like vector, it is meant to exchange array-new[]. Unlike the dynarray which has been proposed from the committee, this does not anticipate compiler/language magic to someway allocate it to the stack when It's a member of the object that is certainly allocated over the stack; it just refers to your “dynamic†or heap-centered array.
std::call_once can also accomplish the same reason. Use either static nearby variables of C++eleven or std::call_once rather than writing your individual double-checked locking for initialization.
