All Implemented Interfaces:

GKRandom, NSObject

Direct Known Subclasses:

GKGaussianDistribution, GKShuffledDistribution

public class GKRandomDistribution
extends NSObject
implements GKRandom

A random distribution is a random source itself with a specific mapping from the input source to the output values. The distribution is uniform, meaning there is no bias towards any of the possible outcomes.

lowestValue

public long lowestValue()

The lowest value the distribution will output.

nextBool

public boolean nextBool()

Description copied from interface: GKRandom

Returns the next true or false value in the random sequence and moves ahead to the next one. The value is either nonzero (true) or zero (false). Use this for simple boolean switches in logic that don't require fuzzy evaluation. For fuzzy evaluation use nextUniform.

By default this should be based on nextIntWithUpperBound:. Implementations may base it on another representation if needed.

Specified by:

nextBool in interface GKRandom

See Also:

nextIntWithUpperBound:, nextUniform

nextInt

public long nextInt()

Description copied from interface: GKRandom

Returns the next integer in the random sequence and moves ahead to the next one. The value is in the range of [INT32_MIN, INT32_MAX]. The lower bits are not guaranteed to be random so please use another property for simple choices.

Specified by:

nextInt in interface GKRandom

See Also:

nextBool, nextUniform

nextIntWithUpperBound

public long nextIntWithUpperBound(long upperBound)

Description copied from interface: GKRandom

Returns the next unsigned value in the random sequence that is less than upperBound. The value is in the range of [0, upperBound). Thus the value never equals or exceeeds upperBound. The unsigned nature and upper bound allows implementations to use logical shifts to return a value whose lower bits are more random than a similar call to nextInt.

This is used to implement nextBool and nextUniform by default.

Specified by:

nextIntWithUpperBound in interface GKRandom

nextUniform

public float nextUniform()

Description copied from interface: GKRandom

Returns the next uniform float in the random sequence and moves ahead to the next one. The value is in the range of [0.0, 1.0]. There is no weighting across the range so remapping this with a curve may give the best sampling distribution for your algorithm.

By default this should be based on nextIntWithUpperBound:. Implementions may base it on another representation if needed.

Specified by:

nextUniform in interface GKRandom

See Also:

nextIntWithUpperBound:, nextInt

numberOfPossibleOutcomes

public long numberOfPossibleOutcomes()

The number of unique possible outcomes, depending on the distribution type this is not always highest - lowest + 1.
