Class DoubleDoublePair

java.lang.Object
de.lmu.ifi.dbs.elki.utilities.pairs.DoubleDoublePair
All Implemented Interfaces:
PairInterface<Double,Double>, Comparable<DoubleDoublePair>
Direct Known Subclasses:
DoubleMinMax
public class DoubleDoublePair extends Object implements Comparable<DoubleDoublePair>, PairInterface<Double,Double>
Pair storing two doubles. Since double is a native type, this can't be done via the
invalid reference 
CPair
generic.
