Class AbstractIndividualFactory<I extends Individual>

java.lang.Object
  org.opt4j.core.AbstractIndividualFactory<I>

Type Parameters:

I - the type of Individual

All Implemented Interfaces:

IndividualFactory

Direct Known Subclasses:

DefaultIndividualFactory

public class AbstractIndividualFactory<I extends Individual>
extends java.lang.Object
implements IndividualFactory

The AbstractIndividualFactory creates Individuals using a given Provider and sets the registered IndividualStateListeners. The Creator is used to create the problem specific Genotype with which the created Individual is initialized.

Field Summary

protected Creator<Genotype>	creator
protected com.google.inject.Provider<I>	individualProvider
protected java.util.Set<IndividualStateListener>	individualStateListeners

Constructor Summary

AbstractIndividualFactory(com.google.inject.Provider<I> individualProvider, Creator<Genotype> creator)
Constructs an AbstractIndividualFactory with a Provider for Individuals.

Method Summary

void	addIndividualStateListener(IndividualStateListener listener) Adds an IndividualStateListener to each Individual that is created by this class.
Individual	create() Creates a new Individual.
Individual	create(Genotype genotype) Creates a new Individual with a specified Genotype.
protected void	injectListeners(java.util.Set<IndividualStateListener> listeners) The IndividualStateListeners will be transmitted to each Individual that is created by this class.
void	removeIndividualStateListener(IndividualStateListener listener) Removes an IndividualStateListener that is invoked if the state of any Individual changes.

Constructor Detail

AbstractIndividualFactory

public AbstractIndividualFactory(com.google.inject.Provider<I> individualProvider,
                                 Creator<Genotype> creator)

Constructs an AbstractIndividualFactory with a Provider for Individuals.

Parameters:

individualProvider - the provider that creates new individuals

creator - the creator that creates random genotypes

Method Detail

injectListeners

@Inject
protected void injectListeners(java.util.Set<IndividualStateListener> listeners)

The IndividualStateListeners will be transmitted to each Individual that is created by this class. The listeners are invoked if the state of the Individual changes.

Parameters:

listeners - the listeners

addIndividualStateListener

public void addIndividualStateListener(IndividualStateListener listener)

Description copied from interface: IndividualFactory

Adds an IndividualStateListener to each Individual that is created by this class. This listener is invoked if the state of the Individual changes.

Specified by:

addIndividualStateListener in interface IndividualFactory

Parameters:

listener - the listener that is invoked if the state of any individual changes

IndividualFactory.removeIndividualStateListener(org.opt4j.core.IndividualStateListener)

create

public Individual create()

Description copied from interface: IndividualFactory

Creates a new Individual.

Specified by:

create in interface IndividualFactory

Returns:

the built individual

create

public Individual create(Genotype genotype)

Description copied from interface: IndividualFactory

Creates a new Individual with a specified Genotype.

Specified by:

create in interface IndividualFactory

Parameters:

genotype - the genotype of the individual

Returns:

the built individual

removeIndividualStateListener

public void removeIndividualStateListener(IndividualStateListener listener)

Description copied from interface: IndividualFactory

Removes an IndividualStateListener that is invoked if the state of any Individual changes. All Individuals created after this method call by this IndividualFactory do no longer use the listener.

Specified by:

removeIndividualStateListener in interface IndividualFactory

Parameters:

listener - the listener that is invoked if the state of any individual changes
