public class CircleGen
extends AbstractFillableBlockShape

Class to generate circle related shapes
The Main purpose of this class is to generate the coordinates based on a shape. The coordinates are organized depending on a Map<ChunkPos, LongOpenHashSet>.

It emply some things:

• The coordinates are divided in chunk
• It uses LongOpenHashSet for several reasons.
  • First, We use a set to avoid doing unnecessary calculations on the shape. It ensures that no duplicate is present.
  • Second, it compresses the BlockPos: The BlockPos are saved under long using LongPosHelper. It saves some memory since that we save four bytes of data for each BlockPos, and there should not have overhead since that we use primitive data type.
  • Third, since that we use primitive data types and that they take less memory, coordinate generation, accession or deletion is much faster than using a Set<BlockPos>. Encoding and decoding blockPos and then adding it into LongOpenHashSetis extremely faster compared to only adding a BlockPos. ~60- 70% facter.

Dividing Coordinates into Chunk has some advantages :

• allow a multithreaded block assignement when using LayerManager
• allow to be used during WG, when using DividedBlockListManager or when placing using ShapePlacer
