Pairs and triples utility classes.
Pairs and triples are frequently used classes and reimplemented too often.
Pair
is the generic non-comparable pair (you can use external comparators!).FCPair
is the generic pair comparable in the first component only.CPair
is the pair comparable in both components.SCPair
is the generic pair comparable in the second component only.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.
