Applying builder patter or similar on a generated class
===

I have the following problem:

A framework generates a class from DB table, each table column is class variable(field).
The generated class has more than 30 fields and just one constructor with no parameters.

To create an instance of that class, I have to use 30 times some setters, which is invitation for inconsistencies. 

I cannot use directly constructors with parameters or Builder pattern, as I cannot edit the generated class. What's the best way to approach this - Wrapper class, thread safe methods, a classic pattern?
