Class NumberOfClustersFormed

java.lang.Object
  net.sourceforge.cilib.measurement.single.NumberOfClustersFormed

All Implemented Interfaces:

Serializable, Measurement, Cloneable

public class NumberOfClustersFormed
extends Object
implements Measurement

This measurement measures the number of clusters that were formed during a particular clustering. For this measurement to work, the following is important:

1. Algorithm.get() should not be null.
2. The algorithm's best solution (best position) should return a Vector.
3. The algorithm's problem's DataSetBuilder should be a ClusterableDataSet.
4. The arrangeClustersAndCentroids() method (defined in ClusterableDataSet) should be implemented to remove empty clusters.
5. The getArrangedClusters() method (defined in ClusterableDataSet) should be implemented to return the list of non-empty clusters.

Method Detail

getClone

public NumberOfClustersFormed getClone()

Description copied from interface: Measurement

Create a cloned copy of the current object and return it. In general the created copy will be a deep copy of the provided instance. As a result this operation an be quite expensive if used incorrectly.

Specified by:

getClone in interface Measurement

Specified by:

getClone in interface Cloneable

Returns:

An exact clone of the current object instance.

Object.clone()

getDomain

public String getDomain()

Description copied from interface: Measurement

Get the domain string representing what this measurement's results will conform to.

Specified by:

getDomain in interface Measurement

Returns:

The Domain String representing the represenation of the measurement

getValue

public Type getValue(Algorithm algorithm)

Description copied from interface: Measurement

Get the value of the measurement. The represenation of the measurement will be based on the domain string defined Measurement.getDomain()

Specified by:

getValue in interface Measurement

Parameters:

algorithm - The algorithm to obtain the measurement from.

Returns:

The Type representing the value of the measurement.
