public class VarlenaUDTTest
extends Object
implements SQLData

A User Defined Type with varlena storage, testing github issue 52. This looks from SQL like an integer type, but is stored in unary: the integer value n is represented by n a characters. That makes it easy to test how big a value gets correctly stored and retrieved. It should be about a GB, but in issue 52 was failing at 32768 because of a narrowing assignment in the native code.
