public class NClobTypeDescriptor extends AbstractTypeDescriptor<NClob>
NClob handling.
Note, nclobs really are mutable (their internal state can in fact be mutated). We simply
treat them as immutable because we cannot properly check them for changes nor deep copy them.| Modifier and Type | Class and Description |
