All Implemented Interfaces:

Comparable<DoubleDistanceSearchCandidate>

public class DoubleMTreeDistanceSearchCandidate
extends DoubleDistanceSearchCandidate

Encapsulates the attributes for a object that can be stored in a heap. The object to be stored represents a node in a M-Tree and some additional information. Additionally to the regular expansion candidate, this object holds the id of the routing object of the underlying M-Tree node and its covering radius.
