Object delete itself from container

Question

So I have a container(any kind, probably std::map or std::vector) which contains objects of a class with some network thing running in a thread that checks if it is still co

Answer 1

In order for the object to delete itself from the container, it will have to know which container it is in. You will need to maintain a pointer to the container in the object. You will also have to protect the container with a lock to stop multiple threads accessing the container at the same time.

I think I prefer your second solution - some managing object looks after removing dead objects from the collection. If nothing else, this will be quite a bit easier to debug and the locking logic becomes centralised in a single object.
