Uses of IRNG in squidpony.squidmath

Subinterfaces of IRNG in squidpony.squidmath

Modifier and Type	Interface and Description
interface	IStatefulRNG Simply groups the two interfaces IRNG and StatefulRandomness so some implementations of IRNG can have their states read from and written to.

Classes in squidpony.squidmath that implement IRNG

Modifier and Type	Class and Description
class	AbstractRNG A helper class for implementing IRNG without so much busy-work.
class	CriticalRNG A type of RNG that can generate values larger or smaller than the normal maximum or minimum, based on a modifier.
class	DeckRNG An RNG variant that has 16 possible grades of value it can produce and shuffles them like a deck of cards.
class	DharmaRNG An alteration to a RandomnessSource that attempts to produce values that are perceived as fair to an imperfect user.
class	DistributedRNG An implementation of IRNG that allows specifying a distribution for all random numbers it produces via a IDistribution.SimpleDistribution value.
class	EditRNG A subclass of StatefulRNG (and thus RNG) that allows customizing many parts of the random number generation.
class	GWTRNG An IRNG implementation that is meant to provide random numbers very quickly when targeting GWT but also to produce the same numbers when used on desktop, Android, or other platforms, and that can have its state read as a StatefulRandomness.
class	MoonwalkRNG An IRNG implementation that allows the extra functionality of a StatefulRandomness and a SkippingRandomness, as well as allowing reverse-lookup of the state that produced a long using the static MoonwalkRNG.inverseNextLong(long) method, and distance checks between two generated numbers with the static MoonwalkRNG.distance(long, long) method.
class	RNG A wrapper class for working with random number generators in a more friendly way.
class	SilkRNG An IStatefulRNG implementation that is meant to provide random numbers very quickly when targeting GWT but also to produce the same numbers when used on desktop, Android, or other platforms, and that can have its state read as a StatefulRandomness; it is thus like GWTRNG but should perform better on recent desktop JVMs.
class	StatefulRNG A slight variant on RNG that always uses a stateful RandomessSource and so can have its state set or retrieved using setState() or getState().
class	TweakRNG Somewhat experimental RNG that can be configured to smoothly transition between producing mostly values in the center of its range, to producing more values at or near the extremes, as well as favoring high or low results.
