net.bmahe.genetics4j.core.spec.chromosome.ImmutableIntChromosomeSpec.Builder

Direct Known Subclasses:

IntChromosomeSpec.Builder

Enclosing class:

ImmutableIntChromosomeSpec

public static class ImmutableIntChromosomeSpec.Builder
extends Object

Builds instances of type ImmutableIntChromosomeSpec. 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 ImmutableIntChromosomeSpec instances.

 new IntChromosomeSpec.Builder()
    .size(int) // required size
    .minValue(int) // required minValue
    .maxValue(int) // required maxValue
    .build();
 

Method Details

from

public final IntChromosomeSpec.Builder from(IntChromosomeSpec instance)

Fill a builder with attribute values from the provided IntChromosomeSpec 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

size

public final IntChromosomeSpec.Builder size(int size)

Initializes the value for the size attribute.

Parameters:

size - The value for size

Returns:

this builder for use in a chained invocation

minValue

public final IntChromosomeSpec.Builder minValue(int minValue)

Initializes the value for the minValue attribute.

Parameters:

minValue - The value for minValue

Returns:

this builder for use in a chained invocation

maxValue

public final IntChromosomeSpec.Builder maxValue(int maxValue)

Initializes the value for the maxValue attribute.

Parameters:

maxValue - The value for maxValue

Returns:

this builder for use in a chained invocation

build

public ImmutableIntChromosomeSpec build()

Builds a new ImmutableIntChromosomeSpec.

Returns:

An immutable instance of IntChromosomeSpec

Throws:

IllegalStateException - if any required attributes are missing

formatRequiredAttributesMessage

private String formatRequiredAttributesMessage()
