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

java.lang.Object

net.bmahe.genetics4j.core.postevaluationprocess.ImmutableFitnessSharing.Builder<T>

Enclosing class:

ImmutableFitnessSharing<T extends Comparable<T>>

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

Builds instances of type ImmutableFitnessSharing. 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 ImmutableFitnessSharing.Builder<T> from(FitnessSharing<T> instance)

Fill a builder with attribute values from the provided FitnessSharing 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

distance

public final ImmutableFitnessSharing.Builder<T> distance(BiFunction<Genotype,Genotype,Double> distance)

Initializes the value for the distance attribute.

Parameters:

distance - The value for distance

Returns:

this builder for use in a chained invocation

sharing

public final ImmutableFitnessSharing.Builder<T> sharing(Function<Double,Double> sharing)

Initializes the value for the sharing attribute.

Parameters:

sharing - The value for sharing

Returns:

this builder for use in a chained invocation

scaleFitness

public final ImmutableFitnessSharing.Builder<T> scaleFitness(BiFunction<Individual<T>,Double,T> scaleFitness)

Initializes the value for the scaleFitness attribute.

Parameters:

scaleFitness - The value for scaleFitness

Returns:

this builder for use in a chained invocation

build

public ImmutableFitnessSharing<T> build()

Builds a new ImmutableFitnessSharing.

Returns:

An immutable instance of FitnessSharing

Throws:

IllegalStateException - if any required attributes are missing

formatRequiredAttributesMessage

private String formatRequiredAttributesMessage()
