{{Tip/Important|Since all objects registered must be singleton, some classes cannot by themselves be registered. Instead, <code>*Type</code> classes are registered and used in the formers' constructors to wrap the flyweight objects. For example, a [[Basics_of_Tile_Entities|<code>TileEntity</code>]] is wrapped via <code>TileEntityType</code>, and <code>Entity</code> is wrapped via <code>EntityType</code>. These <code>*Type</code> classes hold factories that simply create the containing type on demand.
