Class ImmutableIndividual.Builder<T extends Comparable<T>>

java.lang.Object

net.bmahe.genetics4j.core.ImmutableIndividual.Builder<T>

Enclosing class:

ImmutableIndividual<T extends Comparable<T>>

public static final class ImmutableIndividual.Builder<T extends Comparable<T>>
extends Object

Builds instances of type ImmutableIndividual. Initialize attributes and then invoke the build() method to create an immutable instance.

Builder is not thread-safe and generally should not be stored in a field or collection, but instead used immediately to create instances.

Method Details

from

public final ImmutableIndividual.Builder<T> from(Individual<T> instance)

Fill a builder with attribute values from the provided Individual instance. Regular attribute values will be replaced with those from the given instance. Absent optional values will not replace present values.

Parameters:

instance - The instance from which to copy values

Returns:

this builder for use in a chained invocation

genotype

public final ImmutableIndividual.Builder<T> genotype(Genotype genotype)

Initializes the value for the genotype attribute.

Parameters:

genotype - The value for genotype

Returns:

this builder for use in a chained invocation

fitness

public final ImmutableIndividual.Builder<T> fitness(T fitness)

Initializes the value for the fitness attribute.

Parameters:

fitness - The value for fitness

Returns:

this builder for use in a chained invocation

build

public ImmutableIndividual<T> build()

Builds a new ImmutableIndividual.

Returns:

An immutable instance of Individual

Throws:

IllegalStateException - if any required attributes are missing

formatRequiredAttributesMessage

private String formatRequiredAttributesMessage()
