Hi @jbfaden! Thanks for the contribution.

I'd like to know more what's being accomplished here aside from the title. Is it possible to fill in the pull request template? All I see is the boilerplate text still.

[jbfaden]

This is the first time I've written a modification for someone else's code. Where is the pull request template?

I'm working with Jordan, and I see that the library supports 3-index arrays of data but not 4-index arrays. It now supports them as well.

@jbfaden oh, great! So happy to have your help. Thanks for the explanation. That helps me understand the purpose.

FYI, the template is this text that appears at the top of your pull request; see this screenshot:

If you click the ⋯ and choose "Edit", you can replace the text like Brief summary of changes if not sufficiently described by commit messages with something like This adds support for 4-index arrays; replace One of the following should be included here: with the output of mvn test, and so forth.

In any case, this looks fine, so I'm adding my stamp of approval 👍

[jbfaden]

Okay, thanks for pointing that out. Look forward to the next one!

@jbfaden do you have an example product that we can add to our validate regression tests to ensure we can check these? If you have one that should fail, that would be excellent as well!

[jbfaden]

Joe has one, which I assume I could make available to you. I'll ask him.

@jordanpadams sorry if I merged this too quickly—I was excited by this contribution 😊
