de.lmu.ifi.dbs.elki.distance
Class AbstractDistance<D extends AbstractDistance<D>>

java.lang.Object
  de.lmu.ifi.dbs.elki.logging.AbstractLoggable
      de.lmu.ifi.dbs.elki.distance.AbstractDistance<D>

All Implemented Interfaces:

Distance<D>, Loggable, Externalizable, Serializable, Comparable<D>

Direct Known Subclasses:

CorrelationDistance, NumberDistance, SubspaceDistance

abstract class AbstractDistance<D extends AbstractDistance<D>>
extends AbstractLoggable
implements Distance<D>

An abstract distance implements equals conveniently for any extending class. At the same time any extending class is to implement hashCode properly.
