EnumGene (Jenetics 3.8.0)

java.lang.Object
- org.jenetics.EnumGene<A>

All Implemented Interfaces:

Serializable, Comparable<EnumGene<A>>, Gene<A,EnumGene<A>>, Factory<EnumGene<A>>, Verifiable
```
public final class EnumGene<A>
extends Object
implements Gene<A,EnumGene<A>>, Comparable<EnumGene<A>>, Serializable
```
Gene which holds enumerable (countable) genes. Will be used for combinatorial problems in combination with the PermutationChromosome.
The following code shows how to create a combinatorial genotype factory which can be used when creating an Engine instance.
final ISeq<Integer> alleles = ISeq.of(1, 2, 3, 4, 5, 6, 7, 8); final Factory<Genotype<EnumGene<Integer>>> gtf = Genotype.of( PermutationChromosome.of(alleles) );
The following code shows the assurances of the EnumGene.
final ISeq<Integer> alleles = ISeq.of(1, 2, 3, 4, 5, 6, 7, 8); final EnumGene<Integer> gene = new EnumGene<>(5, alleles); assert(gene.getAlleleIndex() == 5); assert(gene.getAllele() == gene.getValidAlleles().get(5)); assert(gene.getValidAlleles() == alleles);
