Interface Generator<T>

Type Parameters:

T - value type

All Superinterfaces:

DataSource<T>, Stringify, Supplier<T>

All Known Subinterfaces:

Cardinality.Fetcher, CopyableGenerator<T>, Distribution.RandomNumbers, Factory<T>, Factory.FactoryGenerator<T>, FlCardinality.FlFetcher, FlDistribution.FlRandom, FlGenerator<T>

All Known Implementing Classes:

AbstractDistributionRandom, AbstractFetcher, AnonymousGenerator, BooleansGenerator, CharactersGenerator, CharactersGenerator.FromString, CharactersGenerator.InRange, DefaultFactory, DistinctGenerator, DoublesGenerator, EagerFetcher, FetcherWithScalar, FilteringGenerator, FlatMappingGenerator, GaussianDistribution.GDRandom, GeneratorQueue, GeneratorWithDistribution, GeneratorWithScalar, LazyFetcher, MappingGenerator, MergingGenerator, MixingGenerator, PermutationsGenerator, RandomIntegersGenerator, RandomizedSequenceGenerator, RepeatingGenerator, RoundRobinGenerator, ShuffledSequenceGenerator, ShufflingGenerator, StringsGenerator, UniformDistribution.UDRandom, ValueGenerator.VG2G

Functional Interface:

This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.

@FunctionalInterface
public interface Generator<T>
extends Supplier<T>, DataSource<T>

Endlessly produces values.

If the generator cannot continue, throws GeneratorException.
