Enclosing class:

ImmutableProgramRandomPrune

public static final class ImmutableProgramRandomPrune.Builder
extends Object

Builds instances of type ImmutableProgramRandomPrune. 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 ImmutableProgramRandomPrune.Builder from(ProgramRandomPrune instance)

Fill a builder with attribute values from the provided ProgramRandomPrune 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

populationMutationProbability

public final ImmutableProgramRandomPrune.Builder populationMutationProbability(double populationMutationProbability)

Initializes the value for the populationMutationProbability attribute.

Parameters:

populationMutationProbability - The value for populationMutationProbability

Returns:

this builder for use in a chained invocation

build

public ImmutableProgramRandomPrune build()

Builds a new ImmutableProgramRandomPrune.

Returns:

An immutable instance of ProgramRandomPrune

Throws:

IllegalStateException - if any required attributes are missing

formatRequiredAttributesMessage

private String formatRequiredAttributesMessage()
