BlockLightStorage, SkyLightStorage
public abstract class LightStorage<M extends ChunkToNibbleArrayMap<M>>
extends SectionDistanceLevelPropagator
LightStorage handles the access, storage and propagation of a specific kind of light within the world. For example, separate instances will be used to store block light as opposed to sky light.

The smallest unit within LightStorage is the section. Sections represent a cube of 16x16x16 blocks and their lighting data. In turn, 16 sections stacked on top of each other form a column, which are analogous to the standard 16x256x16 world chunks.

To avoid allocations, LightStorage packs all the coordinate arguments into single long values. Extra care should be taken to ensure that the relevant types are being used where appropriate.
