Class Tuple

java.lang.Object

net.morimekta.util.Tuple

All Implemented Interfaces:

java.lang.Iterable<java.lang.Object>

Direct Known Subclasses:

Tuple.Tuple1

@Immutable
public class Tuple
extends java.lang.Object
implements java.lang.Iterable<java.lang.Object>

Base class for holding tuples.

A note on tuples in java 8:
This class is mainly meant for holding sets of values passed along in a stream, not as a general holder class. It can be used as a mean of returning tuples of values from methods, though the latter I would really discourage, as it makes the code usually less readable. This would be a moot problem if Java had native tuple handling, but alas.

Example code:

 list.stream()
     .map(i -> tuple(i, ((Integer) i).hashCode())
     .sort(Comparators.comparing(Tuple.Tuple2::second))
     .findFirst()
