public class ClobTypeDescriptor extends AbstractTypeDescriptor<Clob>
Descriptor for Clob handling.
<p/>
Note, clobs 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.

As an example, if this is a JavaTypeDescriptor<Integer> and we are asked to unwrap
the Integer value as a Long we would return something like
<code>Long.valueOf( value.longValue() )</code>.
