PopulationSizeCollector

public PopulationSizeCollector()
Constructs an unattached collector for recording the population size and archive size, if available, from an EvolutionaryAlgorithm.


PopulationSizeCollector

public PopulationSizeCollector(EvolutionaryAlgorithm algorithm)
Constructs a collector for recording the population size and archive size, if available, from the specified EvolutionaryAlgorithm.

Parameters:
algorithm - the algorithm this collector records data from
Method Detail

getAttachPoint

public AttachPoint getAttachPoint()
Description copied from interface: Collector
Returns the attach point describing where this collector is attached. The matched object should be unique.

Specified by:
getAttachPoint in interface Collector
Returns:
the attach point describing where this collector is attached

attach

public Collector attach(Object object)
Description copied from interface: Collector
Returns a new instance of this collector which has been attached to the specified object as identified by the attach point returned through Collector.getAttachPoint().

Specified by:
attach in interface Collector
Parameters:
object - the matching object
Returns:
a new instance of this collector which has been attached to the specified object

collect

public void collect(Accumulator accumulator)
Description copied from interface: Collector
Collects the necessary information from the object, storing the data to the specified accumulator. This method must only be invoked after this collector has been attached to an appropriate object.

Specified by:
collect in interface Collector
Parameters:
accumulator - the accumulator to which the collected data is stored
