Class Int3ObjectOpenHashMap<V>

java.lang.Object

com.hypixel.hytale.math.data.Int3ObjectOpenHashMap<V>

Type Parameters:

V - value type (must not be null)

public class Int3ObjectOpenHashMap<V>
extends Object

Open-addressed hash map keyed by three int coordinates (x, y, z).

Keys are stored in a single stride-based int[] array ([x0, y0, z0, x1, y1, z1, ...]) to minimize field lookups and keep each entry's coordinates on the same cache line. Uses linear probing with backward-shift deletion (no tombstones). Null values are disallowed; a null in the values array indicates an empty slot.

Hashing uses Fibonacci hashing (Knuth 1973 — multiply by the golden-ratio constant, take top bits) which provides near-uniform slot distribution for sequential and clustered keys. The three coordinates are mixed via a MurmurHash3 64-bit finalizer (fmix64) before the Fibonacci index step.

Not thread-safe.
