Class GenericMTreeDistanceSearchCandidate

java.lang.Object

de.lmu.ifi.dbs.elki.index.tree.query.GenericMTreeDistanceSearchCandidate

All Implemented Interfaces:

Comparable<GenericMTreeDistanceSearchCandidate>

public class GenericMTreeDistanceSearchCandidate
extends Object
implements Comparable<GenericMTreeDistanceSearchCandidate>

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. FIXME: Class naming in this package is inconsistent.
