Class ImmutableRule.Builder

java.lang.Object

net.bmahe.genetics4j.gp.spec.mutation.ImmutableRule.Builder

Enclosing class:

ImmutableRule

public static final class ImmutableRule.Builder
extends Object

Builds instances of type ImmutableRule. 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 ImmutableRule.Builder from(Rule instance)

Fill a builder with attribute values from the provided Rule 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

predicate

public final ImmutableRule.Builder predicate(Predicate<TreeNode<Operation<?>>> predicate)

Initializes the value for the predicate attribute.

Parameters:

predicate - The value for predicate

Returns:

this builder for use in a chained invocation

applicator

public final ImmutableRule.Builder applicator(BiFunction<Program,TreeNode<Operation<?>>,TreeNode<Operation<?>>> applicator)

Initializes the value for the applicator attribute.

Parameters:

applicator - The value for applicator

Returns:

this builder for use in a chained invocation

build

public ImmutableRule build()

Builds a new ImmutableRule.

Returns:

An immutable instance of Rule

Throws:

IllegalStateException - if any required attributes are missing

formatRequiredAttributesMessage

private String formatRequiredAttributesMessage()
