Uses of AbstractDatabaseDistanceFunction in de.lmu.ifi.dbs.elki.distance.distancefunction

Subclasses of AbstractDatabaseDistanceFunction in de.lmu.ifi.dbs.elki.distance.distancefunction

Modifier and Type	Class and Description
class	AbstractDBIDRangeDistanceFunction Abstract base class for distance functions that rely on integer offsets within a consecutive range.
class	AbstractIndexBasedDistanceFunction<O,F extends IndexFactory<O>> Abstract super class for distance functions needing a database index.
class	RandomStableDistanceFunction This is a dummy distance providing random values (obviously not metrical), useful mostly for unit tests and baseline evaluations: obviously this distance provides no benefit whatsoever.
class	SharedNearestNeighborJaccardDistanceFunction<O> SharedNearestNeighborJaccardDistanceFunction computes the Jaccard coefficient, which is a proper distance metric.
