If you don't have the XClass (or Class) yet you need indeed first get a Class
reference and then via the ReflectionManager (mappings#getReflectionManager())
get the XClass. Then you use the XClass api.

I am not sure you can. I think the class is more of a container on which you set
properties and then at some stage you call #make(). Do you need to do this annotation
processing at a specific point in time?
Maybe you could do the processing in SimpleValueBinder#setType. There you are already
dealing with XProperty and there is a fair amount of annotation processing going on.
Not sure whether this is suitable in your case.
