Update On Groovy Validators 2014-06-25

I am working on my Groovy validators.

I think I found a way to get them to work with immutable objects. They are actually pseudo-immutable. I do not prevent subclassing. The fields are not final; the setters can be called, but nothing happens. Also, it only works with the Map constructor.

I did it all with Java annotations. I tried doing some AST transformation. That is a few hours of my life I will not get back.

I will work on it for a few more days, and perhaps announce it on the Groovy mailing list. Perhaps someone will help with AST transformation.

The Groovy website is being changed. Perhaps the new website will go into more detail about AST.
