<p>Implementations do not necessarily read the memory snapshot data prior to this method being called. Memory snapshot data may be loaded lazily and may be discarded after being passed to the delegate. This provides clean memory management without burdening a snapshot implementation with the requirement that it track all memory region data simultaneously.</p>
