Uses of IPointHash in squidpony.squidmath

Subinterfaces of IPointHash in squidpony.squidmath

Modifier and Type	Interface	Description
interface	FlawedPointHash	An interface for point hashes that are statistically biased, as well as a holder for inner classes that implement this.

Classes in squidpony.squidmath that implement IPointHash

Modifier and Type	Class	Description
static class	FlawedPointHash.CubeHash	Very similar to FlawedPointHash.QuiltHash, but this doesn't change the pattern in different large squares, and instead repeats a square or cube of symmetric and patterned results over and over (so it can be tiled).
static class	FlawedPointHash.FNVHash	FNV32a is OK as a hash for bytes when used in some hash tables, but it has major issues on its low-order bits when used as a point hash (the high bits aren't much better).
static class	FlawedPointHash.QuiltHash	Extremely flawed if you're using this as a point hash, but meant to be aesthetically interesting, this produces different symmetrical patterns in squares, as if on a quilt.
static class	FlawedPointHash.RugHash	Produces hashes that show strong bias on one axis (usually the later axes matter more) and have nice-looking patterns of dots.
class	GoldPointHash	A relatively simple IPointHash that multiplies each of the x, y, etc.
class	HastyPointHash	A group of similar methods for getting hashes of points based on long coordinates in 2, 3, 4, or 6 dimensions and a long for state; like PointHash but faster and maybe not as high-quality.
class	IntPointHash	A group of similar methods for getting hashes of points based on int coordinates in 2, 3, 4, or 6 dimensions and an int for state; the code is similar to HastyPointHash but will be much faster on GWT.
static class	IPointHash.IntImpl	A convenience abstract class to implement IPointHash when you have an int for state.
static class	IPointHash.LongImpl	A convenience abstract class to implement IPointHash when you have a long for state.
class	PointHash	A group of similar methods for getting hashes of points based on long coordinates in 2, 3, 4, or 6 dimensions and a long for state.
