The only documentation on getValue() on https://api.drupal.org/api/drupal/core%21lib%21Drupal%21Core%21TypedData... is that it "Gets the data value."

While technically I guess its accurate, the implementation here adds logic that could do with an explanation. For example, it introduces logic to ignore Computed properties. Why? It would be helpful to put some of that here so people who stumble across have an idea of what's going on.

We ran into a problem recently with a custom field type and the interaction with Inline Entity Form.

It just seems that Computed properties are part of the "value" of a FieldItem, and some documentation would have helped us make a decision about which direction to go.

+1 always for better documention. This might also be a usecase where FieldItemlistInterface should override the method to provide a better documentation.

Here is some documentation that I would have found helpful. As mentioned in #2, it might be better to put this in FieldItemListInterface.

YES! When I was starting in Drupal knowing this would of been nice.

I agree with both you that FieldItemListInterface seems like a good place though.

Version: 10.1.x-dev » 11.x-dev

Drupal core is moving towards using a “main” branch. As an interim step, a new 11.x branch has been opened, as Drupal.org infrastructure cannot currently fully support a branch named main. New developments and disruptive changes should now be targeted for the 11.x branch, which currently accepts only minor-version allowed changes. For more information, see the Drupal core minor version schedule and the Allowed changes during the Drupal core release cycle.
