Enclosing class:

ImmutableElitism

@Generated(from="Elitism",
           generator="Immutables")
public static class ImmutableElitism.Builder
extends Object

Builds instances of type Elitism. 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.

Constructor Details

Builder

public Builder()

Creates a builder for Elitism instances.

 new Elitism.Builder()
    .offspringSelectionPolicy(net.bmahe.genetics4j.core.spec.selection.SelectionPolicy) // required offspringSelectionPolicy
    .atLeastNumOffsprings(int) // optional atLeastNumOffsprings
    .survivorSelectionPolicy(net.bmahe.genetics4j.core.spec.selection.SelectionPolicy) // required survivorSelectionPolicy
    .atLeastNumSurvivors(int) // optional atLeastNumSurvivors
    .offspringRatio(double) // optional offspringRatio
    .build();
 

Method Details

from

public final Elitism.Builder from(Elitism instance)

Fill a builder with attribute values from the provided Elitism 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

offspringSelectionPolicy

public final Elitism.Builder offspringSelectionPolicy(SelectionPolicy offspringSelectionPolicy)

Initializes the value for the offspringSelectionPolicy attribute.

Parameters:

offspringSelectionPolicy - The value for offspringSelectionPolicy

Returns:

this builder for use in a chained invocation

atLeastNumOffsprings

public final Elitism.Builder atLeastNumOffsprings(int atLeastNumOffsprings)

Initializes the value for the atLeastNumOffsprings attribute.

If not set, this attribute will have a default value as returned by the initializer of atLeastNumOffsprings.

Parameters:

atLeastNumOffsprings - The value for atLeastNumOffsprings

Returns:

this builder for use in a chained invocation

survivorSelectionPolicy

public final Elitism.Builder survivorSelectionPolicy(SelectionPolicy survivorSelectionPolicy)

Initializes the value for the survivorSelectionPolicy attribute.

Parameters:

survivorSelectionPolicy - The value for survivorSelectionPolicy

Returns:

this builder for use in a chained invocation

atLeastNumSurvivors

public final Elitism.Builder atLeastNumSurvivors(int atLeastNumSurvivors)

Initializes the value for the atLeastNumSurvivors attribute.

If not set, this attribute will have a default value as returned by the initializer of atLeastNumSurvivors.

Parameters:

atLeastNumSurvivors - The value for atLeastNumSurvivors

Returns:

this builder for use in a chained invocation

offspringRatio

public final Elitism.Builder offspringRatio(double offspringRatio)

Initializes the value for the offspringRatio attribute.

If not set, this attribute will have a default value as returned by the initializer of offspringRatio.

Parameters:

offspringRatio - The value for offspringRatio

Returns:

this builder for use in a chained invocation

build

public Elitism build()

Builds a new Elitism.

Returns:

An immutable instance of Elitism

Throws:

IllegalStateException - if any required attributes are missing

atLeastNumOffspringsIsSet

private boolean atLeastNumOffspringsIsSet()

atLeastNumSurvivorsIsSet

private boolean atLeastNumSurvivorsIsSet()

offspringRatioIsSet

private boolean offspringRatioIsSet()

formatRequiredAttributesMessage

private String formatRequiredAttributesMessage()
