Constructor Details

AbstractIndividualFactory

public AbstractIndividualFactory(com.google.inject.Provider<I> individualProvider,
 Creator 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 Details

injectListeners

@Inject
protected void injectListeners(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

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
