Direct Known Subclasses:

GenerationalReplacement.Builder

Enclosing class:

ImmutableGenerationalReplacement

public static class ImmutableGenerationalReplacement.Builder
extends Object

Builds instances of type ImmutableGenerationalReplacement. 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.

Builder

public Builder()

Creates a builder for ImmutableGenerationalReplacement instances.

 new GenerationalReplacement.Builder()

    .build();
 

Method Details

from

public final GenerationalReplacement.Builder from(GenerationalReplacement instance)

Fill a builder with attribute values from the provided GenerationalReplacement 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 GenerationalReplacement.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

build

public ImmutableGenerationalReplacement build()

Builds a new ImmutableGenerationalReplacement.

Returns:

An immutable instance of GenerationalReplacement

Throws:

IllegalStateException - if any required attributes are missing
