Streamer around an arbitrary STL like container, which implements basic container functionality.

Note:

Although this class contains all the setup necessary to deal with maps, the map-like functionality is NOT supported. For optimization reasons this functionality is put into the class TEmulatedMapProxy.

typedef void *(* TVirtualCollectionProxy::CopyIterator_t) (void *dest, const void *source)

Copy the iterator source into dest.

dest should contain the location of a memory arena of size fgIteratorArenaSize. If iterator-specific information is of that size or less, the iterators will be constructed in place in the given locations. Otherwise, iterators will be allocated via new and their address returned by modifying the value of *begin_arena and *end_arena. The actual address of the iterator is returned in any case.

If iterator-specific information is of that size or less, the iterators will be constructed in place in the given locations. Otherwise, iterators will be allocated via new and their address returned by modifying the value of *begin_arena and *end_arena. As a special case, given that iterators for array-backed containers are just pointers, the required information will be directly stored in *(begin|end)_arena.

iter and end should be pointers to an iterator to be incremented and an iterator that points to the end of the collection, respectively.

If iter has not reached the end of the collection, this function increments the iterator and returns a pointer to the element before the increment. Otherwise, nullptr is returned.
