Package org.neo4j.gds.core.compression.packed

Class PackedTailPacker

java.lang.Object

org.neo4j.gds.core.compression.packed.PackedTailPacker

public final class PackedTailPacker
extends java.lang.Object

Compresses values in blocks of AdjacencyPacking.BLOCK_SIZE using bit-packing.

If a block to compress has less than AdjacencyPacking.BLOCK_SIZE values, this strategy uses a loop-based packing approach to compress the values in that block.
