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

java.lang.Object

io.jenetics.AbstractChromosome<G>

Type Parameters:

G - the gene type.

All Implemented Interfaces:

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

Direct Known Subclasses:

AbstractTreeChromosome, AnyChromosome, BigIntegerChromosome, CharacterChromosome, DoubleChromosome, IntegerChromosome, LongChromosome, PermutationChromosome

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

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 Details

_genes

protected final 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 Details

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 Details

get

public G get(int index)

Description copied from interface: BaseSeq

Return the value at the given index.

Specified by:

get in interface BaseSeq<G extends Gene<?,G>>

Parameters:

index - index of the element to return.

Returns:

the value at the given index.

length

public int length()

Description copied from interface: BaseSeq

Return the length of this sequence. Once the sequence is created, the length can't be changed.

Specified by:

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

Returns:

the length of this sequence.

isValid

public boolean isValid()

Description copied from interface: Verifiable

Check if this object is valid.

Specified by:

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

Specified by:

isValid in interface Verifiable

Returns:

true if this object is valid, false otherwise.

hashCode

public int hashCode()

Overrides:

hashCode in class Object

equals

public boolean equals(Object obj)

Overrides:

equals in class Object

toString

public String toString()

Overrides:

toString in class Object
