Base model AnyURI java binding is to string

[pahjbo]

The java binding to AnyURI is just string - this is was an early compromise as then attributes that use it have lost all idea that it is a URI - not sure how to resolve this immediately though as trying to use java.net.URI is difficult as it is clearly not a Java primitive

probably needs a hand written class to make it look like the auto-generated "primitives"

I'm not a big fan of code-gen so take this with a grain of salt :-)

Q. How do you deal with ivoa base model "primitives" that are allowed to be null?

java.lang.String is not a primitive either... yet we have strings.

In normal java code (aka "good java code" IMO), if a primitive like a double is allowed to be null you use java.lang.Double and if it can never be null you can in principle use the actual primitive (double) or you could use the immutable wrapper and enforce the not-null another way.

Is java.net.URI that much different?

In the fairly near future generated code will be the predominant form of code (perhaps it already is) Having our own code generation platforms is a way of retaining a bit of control over the structure.

The "genuine" java primitives have auto-boxing so there is more freedom in using them interchangeably with the object forms.

This issue is really a marker that URI is not being treated by the tooling in a way that preserves its specialness - I think that the mapping to string might have been an early convenience that was not flagged with a "FIXME" and then forgotten.
