Class IndicatorCollector

java.lang.Object
  org.moeaframework.analysis.collector.IndicatorCollector

All Implemented Interfaces:

Collector

public class IndicatorCollector
extends Object
implements Collector

Collects performance indicator values from an Algorithm.

Constructor Summary

IndicatorCollector(Indicator indicator)
Constructs an unattached collector for recording performance indicator values from an algorithm.

IndicatorCollector(Indicator indicator, EpsilonBoxDominanceArchive archive)
Constructs an unattached collector for recording performance indicator values from an algorithm, with an ε-box dominance archive to prune the approximation set to a desired resolution.

IndicatorCollector(Indicator indicator, EpsilonBoxDominanceArchive archive, Algorithm algorithm)
Constructs a collector for recording performance indicator values from the specified algorithm.

Method Summary

Collector	attach(Object object) 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().
void	collect(Accumulator accumulator) Collects the necessary information from the object, storing the data to the specified accumulator.
AttachPoint	getAttachPoint() Returns the attach point describing where this collector is attached.

Method Detail

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

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
