All Implemented Interfaces:

HierarchicalResult, Result

public class PointerDensityHierarchyRepresentationResult
extends PointerHierarchyRepresentationResult

Extended pointer representation useful for HDBSCAN. In addition to the parent object and the distance to the parent, it also includes the core distance, which is a density estimation.
