Represents a set of block positions (long representation).
Uses a Long2LongLinkedOpenHashMap
as its internal storage medium
to facilitate the quick addition and removal of block positions.
Positions are index into a 2x cubed area that then stores as a long, a bitset representing which positions within that area are currently set.
This has two major advantages:
- Positions that are geometrically close together are grouped together in memory. This localises adjacent reads and writes.
- A larger number of positions can be comprised together into one long allowing for a smaller memory footprint.
