Class AbstractChromosome<G extends Gene<?,G>>

java.lang.Object

org.jenetics.AbstractChromosome<G>

Type Parameters:

G - the gene type.

All Implemented Interfaces:

Serializable, Iterable<G>, RandomAccess, Chromosome<G>, Factory<Chromosome<G>>, Verifiable

Direct Known Subclasses:

AnyChromosome, CharacterChromosome, DoubleChromosome, IntegerChromosome, LongChromosome, PermutationChromosome

public abstract class AbstractChromosome<G extends Gene<?,G>>
extends Object
implements Chromosome<G>, RandomAccess, Serializable

The abstract base implementation of the Chromosome interface. The implementors of this class must assure that the protected member _genes is not null and the length of the genes > 0.

Field Detail

_genes

protected transient ISeq<G extends Gene<?,G>> _genes

Array of genes which forms the chromosome. This array must be initialized by the derived classes.

_valid

protected transient Boolean _valid

Indicates whether this chromosome is valid or not. If the variable is null the validation state hasn't been calculated yet.

Constructor Detail

AbstractChromosome

protected AbstractChromosome(ISeq<? extends G> genes)

Create a new AbstractChromosome from the given genes array.

Parameters:

genes - the genes that form the chromosome.

Throws:

NullPointerException - if the given gene array is null.

IllegalArgumentException - if the length of the gene sequence is empty.

Method Detail

getGene

public G getGene(int index)

Description copied from interface: Chromosome

Return the gene on the specified index.

Specified by:

getGene in interface Chromosome<G extends Gene<?,G>>

Parameters:

index - The gene index.

Returns:

the wanted gene.

toSeq

public ISeq<G> toSeq()

Description copied from interface: Chromosome

Return an unmodifiable sequence of the genes of this chromosome.

Specified by:

toSeq in interface Chromosome<G extends Gene<?,G>>

Returns:

an immutable gene sequence.

isValid

public boolean isValid()

Description copied from interface: Verifiable

Check if this object is valid.

Specified by:

isValid in interface Verifiable

Returns:

true if this object is valid, false otherwise.

iterator

public Iterator<G> iterator()

Specified by:

iterator in interface Iterable<G extends Gene<?,G>>

length

public int length()

Description copied from interface: Chromosome

Returns the length of the Chromosome. The minimal length of a chromosome is one.

Specified by:

length in interface Chromosome<G extends Gene<?,G>>

Returns:

Length of the Chromosome
