RawEntityStore Class

A RawEntityStore enables using an entity store without using Entity's.

public sealed class RawEntityStore : Friflo.Engine.ECS.EntityStoreBase

Inheritance System.Object 🡒 EntityStoreBase 🡒 RawEntityStore

Remarks

The focus of the this entity store implementation is performance.
The key is to minimize heap consumption required by EntityNode's - 48 bytes
A RawEntityStore stores only an array of blittable Friflo.Engine.ECS.RawEntityNode's - structs having no reference type fields.

The downside of this approach are:

• Entities can be created only programmatically but not within the editor which requires (managed) Entity's.
• The API to access / query / mutate Friflo.Engine.ECS.RawEntityNode's is less convenient.
  It requires always two parameters - a RawEntityStore + entity id - instead of a single Entity reference.
