Extension Reference

Extensions are marker interfaces that opt a SuperBlockEntityBehaviour into additional systems. They're picked up lazily and cached per block entity, so behaviours that don't implement a given extension have zero impact on that system's cost.

For more about SuperBlockEntityBehaviours, see [Super Block Entity Behaviours](./Super Behaviours.md).
