So I have a class generated by some contract (so no modifications allowed) with multiple data layers, I get it through soap request and then in my backend I have something like this:
value = bigRequest.getData().getSamples().get(0).getValuableData().getValue()
and in every dereference in that chain I can have null result. Class itself has no logic, just pure data with accessors, but nonetheless. I'm kinda sick of thought to make an ugly boilerplate of not-null checks for every single dereference, so I'm thinking of the best practice here:
- Actually make the ugly boilerplate (either with ifs or with asserts). I assume that its what I've got to do, but I have faint hopes.
- Do some Optional magic. But with no access to modify the source it'll probably be even uglier.
- Catch the NPE. It's ugly in its heart, but in this particular case I feel it's the best option, just because it's part of the logic, either I have that value or not. But catching NPE makes me shiver.
- Something I can't see by myself now.
I'm actually feel myself a little bit uncomfortable with this question cause I feel that NPE theme is explored to the bones, but I had no success in search.
