net.bmahe.genetics4j.neat.spec.ImmutableNeatChromosomeSpec.Builder

Direct Known Subclasses:

NeatChromosomeSpec.Builder

Enclosing class:

ImmutableNeatChromosomeSpec

public static class ImmutableNeatChromosomeSpec.Builder
extends Object

Builds instances of type ImmutableNeatChromosomeSpec. 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 ImmutableNeatChromosomeSpec instances.

 new NeatChromosomeSpec.Builder()
    .numInputs(int) // required numInputs
    .numOutputs(int) // required numOutputs
    .minWeightValue(float) // required minWeightValue
    .maxWeightValue(float) // required maxWeightValue
    .build();
 

Method Details

from

public final NeatChromosomeSpec.Builder from(NeatChromosomeSpec instance)

Fill a builder with attribute values from the provided NeatChromosomeSpec 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

numInputs

public final NeatChromosomeSpec.Builder numInputs(int numInputs)

Initializes the value for the numInputs attribute.

Parameters:

numInputs - The value for numInputs

Returns:

this builder for use in a chained invocation

numOutputs

public final NeatChromosomeSpec.Builder numOutputs(int numOutputs)

Initializes the value for the numOutputs attribute.

Parameters:

numOutputs - The value for numOutputs

Returns:

this builder for use in a chained invocation

minWeightValue

public final NeatChromosomeSpec.Builder minWeightValue(float minWeightValue)

Initializes the value for the minWeightValue attribute.

Parameters:

minWeightValue - The value for minWeightValue

Returns:

this builder for use in a chained invocation

maxWeightValue

public final NeatChromosomeSpec.Builder maxWeightValue(float maxWeightValue)

Initializes the value for the maxWeightValue attribute.

Parameters:

maxWeightValue - The value for maxWeightValue

Returns:

this builder for use in a chained invocation

build

public ImmutableNeatChromosomeSpec build()

Builds a new ImmutableNeatChromosomeSpec.

Returns:

An immutable instance of NeatChromosomeSpec

Throws:

IllegalStateException - if any required attributes are missing

formatRequiredAttributesMessage

private String formatRequiredAttributesMessage()
