Package elki.distance

Class AbstractDBIDRangeDistance

  • All Implemented Interfaces:
    elki.distance.DBIDDistance, elki.distance.DBIDRangeDistance, elki.distance.Distance<elki.database.ids.DBID>
    public abstract class AbstractDBIDRangeDistance
extends AbstractDatabaseDistance<elki.database.ids.DBID>
implements elki.distance.DBIDRangeDistance
    Abstract base class for distance functions that rely on integer offsets within a consecutive range. This is beneficial for external distances.
