A Pair is a container that holds two related objects. It is the equivalent of an Association in Smalltalk, or an implementation of Map.Entry in the JDK. A Twin is a Pair with the same types. This class is a factory class for Pairs and Twins. A Triple is a container that holds three related objects. Similar to Haskell a Tuple is container that can contain 2 or more objects. The Triple is the implementation of the 3-tuple. A Triplet is a Triple with the same types. This class holds factory methods for Triples and Triplets The equivalent class for primitive and object combinations is org.eclipse.collections.impl.tuple.primitive.PrimitiveTuples
