32  * Specifies that a persistent property or field should be persisted
33  * as a large object to a database-supported large object type.
34  * The <code>Lob</code> annotation may be used in conjunction
35  * with the {@link Basic} annotation. A <code>Lob</code> may be
36  * either a binary or character type.
37  *
38  * <p> The <code>Lob</code> type is inferred from the type of the
39  * persistent field or property, and except for string and
40  * character-based types defaults to Blob.
