Pairs and triples utility classes.

*

Pairs and triples are frequently used classes and reimplemented too often.

* * * *

Due to limitations in object subclassing, {@link de.lmu.ifi.dbs.elki.utilities.pairs.CPair CPair} cannot be * a subclass of {@link de.lmu.ifi.dbs.elki.utilities.pairs.FCPair FCPair}, since a class cannot implement * the Comparable interface twice.

* *

Also primitive types cannot be used in Generics, resulting in the following classes for primitive types:

* * * *

Triples can be used via:

* * *

If you need a triple comparable in just particular components, either define a comparator for sorting * or subclass Triple appropriately.
