Triple<FIRST,SECOND,THIRD> | Triple without comparison. |
Pairs and triples utility classes.
Pairs and Triples are frequently used classes and reimplemented too often.
Pair
is the generic non-comparable pair.FCPair
is the generic pair comparable in the first component only.FCPair
is the pair comparable in both components.Due to limitations in object subclassing, CPair
cannot be
a subclass of 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:
IntIntPair
storing two int
valuesDoubleIntPair
storing one double
and one int
value.IntDoublePair
storing one int
and one double
value.DoubleDoublePair
storing two double
valuesTriples can be used via:
If you need a triple comparable in just particular components, either define a comparator for sorting or subclass Triple appropriately.
