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

Enclosing class:

ImmutableBitChromosomeSpec

public static final class ImmutableBitChromosomeSpec.Builder
extends Object

Builds instances of type ImmutableBitChromosomeSpec. 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 ImmutableBitChromosomeSpec.Builder from(BitChromosomeSpec instance)

Fill a builder with attribute values from the provided BitChromosomeSpec 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

numBits

public final ImmutableBitChromosomeSpec.Builder numBits(int numBits)

Initializes the value for the numBits attribute.

Parameters:

numBits - The value for numBits

Returns:

this builder for use in a chained invocation

build

public ImmutableBitChromosomeSpec build()

Builds a new ImmutableBitChromosomeSpec.

Returns:

An immutable instance of BitChromosomeSpec

Throws:

IllegalStateException - if any required attributes are missing

formatRequiredAttributesMessage

private String formatRequiredAttributesMessage()
