This is not an entity component system. ECS defines how you need to structure your code. You have basic entities that you can assign components to. If you add certain components to entities then some systems will handle logic for all entities that have some subset of components. Entities that do not have the required set of components will be ignored. ECS can usually benefit from these types of allocators as they provide performance benefits but it isn't required.
