Package org.uma.evolver.parameter.factory

Interface ParameterFactory<S extends org.uma.jmetal.solution.Solution<?>>

Type Parameters:

S - The type of solution this factory creates parameters for

All Known Implementing Classes:

BinaryParameterFactory, DoubleParameterFactory, MOPSOParameterFactory, PermutationParameterFactory

Functional Interface:

This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.

@FunctionalInterface
public interface ParameterFactory<S extends org.uma.jmetal.solution.Solution<?>>

A factory interface for creating CategoricalParameter instances specific to different types of solutions.

This interface serves as the base for creating type-safe parameter factories for various solution representations (e.g., binary, permutation, real-valued) in evolutionary algorithms. Implementations of this interface provide concrete parameter creation logic tailored to specific solution types.

Key features:

• Type-safe parameter creation through generics
• Centralized parameter instantiation
• Support for different solution representations
• Flexible configuration through string-based parameter names

Implementations should handle the creation of all necessary parameters for configuring evolutionary algorithm components such as variation operators, selection mechanisms, and archiving strategies.

Method Details

createParameter

CategoricalParameter createParameter(String parameterName,
 List<String> values)

Creates and returns a specific CategoricalParameter instance based on the provided parameter name.

This method serves as a factory for creating different types of parameters used in configuring evolutionary algorithms. The actual type of parameter created depends on the parameterName.

Parameters:

parameterName - the name of the parameter to create (case-sensitive)

values - the list of possible string values for the parameter (must not be null or empty)

Returns:

an instance of CategoricalParameter corresponding to the specified parameter name

Throws:

IllegalArgumentException - if the values list is null or empty
