Interface IClusterer

All Known Implementing Classes:

AverageLinkClusterer, CompleteLinkClusterer, SingleLinkClusterer

public interface IClusterer

An interface describing a cluster facility. The clusterer gets a set of Objects and a distance calculator and returns a (possibly nested) set of clusters, each containing a number of the original Objects.

Method Summary

void	calculateClusters(java.util.Set Objects, SimilarityComparatorListener DistanceCalculator) A method clustering a set of objects, given a distance calculator upon pairs of these objects.
Graph	getHierarchy() Returns the (calculated) hierarchy of the clusters.

Method Detail

calculateClusters

void calculateClusters(java.util.Set Objects,
                       SimilarityComparatorListener DistanceCalculator)

A method clustering a set of objects, given a distance calculator upon pairs of these objects.

Parameters:

Objects - The set of objects to cluster.

DistanceCalculator - The similarity comparison event listener object, that actually performs the similarity calculation.

getHierarchy

Graph getHierarchy()

Returns the (calculated) hierarchy of the clusters. For non-hierarchical algorithms, there will be no edges in the graph.

Returns:

The hierarchy as a Graph.
