Class Cluster

java.lang.Object
  dbStat.Cluster

public class Cluster

extends java.lang.Object

Cluster class that clusters all proximal vectors.

The collection of vectors is a unique set of attribute vectors that have been associated with the centroid vector of this cluster.

Field Summary

private AttributeVector	centroid an AttributeVector that represents the center of the cluster
private int	identity an integer to track and identify this unique cluster
private java.util.ArrayList	vectorList the list of AttributeVectors in the cluster

Constructor Summary

Cluster(AttributeVector firstVector)
Constructor for the class creates a cluster with its first vector and sets this first vector as its centroid

Method Summary

void	addAttributeVector(AttributeVector attVector) Add a new vector to the cluster if it doesn't already exist in the cluster
void	calculateCentroid() Method to calculate the centroid for the cluster
AttributeVector	getCentroid() Gets the centroid vector for this cluster
int	getClusterSize() Gets the number of vectors this cluster contains
AttributeVector	getVectorByIndex(int index) Gets the attribute vector located at the specified index
void	removeAttributeVector(java.lang.String vectorID) Removes a given AttributeVector from the cluster
java.lang.String	toString()
