public class HM_SingleLink
extends HM_Cluster

Provides one implementation of a clustering process. This class can be used to evaluate two values of a simple type (int, float, string) and records the closest distance. The parent service can then use this to create a permanent link between itself and the service that the matching dataset belongs to.

If there is no overlap in the datasets, a zero result is returned, meaning that no clustering is possible. A Euclidean distance metric is used to measure closeness. This service then tries to link its parent service with all other ones that are part of the linked set, or cluster group.
