Interface Dendrogram<S extends ClusterStep>

All Superinterfaces:

java.lang.Iterable<DendrogramIterator<S>>

All Known Implementing Classes:

DendrogramBase

public interface Dendrogram<S extends ClusterStep>
extends java.lang.Iterable<DendrogramIterator<S>>

A basic interface for a dendrogram. A dendrogram is a hierarchical structure that shows a hierarchy of clusters. For example what clusters were merged to form a bigger cluster, which may be merged some ClusterSteps later.
The interface itself only provides some basic query methods and an iterator access using DendrogramIterator.
