A tuple, e.g. a 2-ary Tuple, can be converterted to a an arbitrary instance using tuple.to((v1, v2) -> new Something(v1, v2), or more succinct: tuple.to(Something::new). This is a convenience API which eliminates the need to "manually extract" each value of the tuple, and instead either freely name the values with a lambda, or directly have the values passed to a method reference with the equivalent parameter signature as the parameterized types of the tuple.
Changes in license headers in .java files is because mathieucarbou/license-maven-plugin#118
It's is not available to resolve previous version itself when we use non-numeric LOCAL-SNAPSHOT for building Run with: mvn japicmp:cmp -Djapicmp.oldversion=<last released version>

There was a problem hiding this comment.
This is just a dummy class used to test converting from XTuple to an arbitrary type.

Kult det console-scriptet! :D |

Jepp, det er aktuelt i noen sammenhenger 😅 |

New feature:
Add facility to convert tuples (triples, quadruples, etc) to arbitrary instances using either method references (typically a constructor
A::new) having the same parameter type signature as the parameterized types of the tuple, or a lambda. Using a lambda enables arbitrary naming when referring to the constituents of the tuple, and a method reference offers a succinct conversion without needing to refer to internals of the tuple at all.As usual, the use of tuples should only be used by particularly general code. Most often a custom class with fields offering more semantics of the values is in order.

All of the .java sources are touched because of a change in the license-maven-plugin, and can basically be ignored, as they all have this as their only diff:
