| /** |
| * Specifies that a persistent property or field should be persisted |
| * as a large object to a database-supported large object type. |
| * |
| * <p> Portable applications should use the <code>Lob</code> annotation |
| * when mapping to a database Lob type. The <code>Lob</code> |
| * annotation may be used in conjunction with the {@link Basic} |
| * annotation or the {@link ElementCollection} annotation when the |
| * element collection value is of basic type. A <code>Lob</code> may |
| * be either a binary or character type. |
| * |
| * <p> The <code>Lob</code> type is inferred from the type of the |
| * persistent field or property, and except for string and |
| * character-based types defaults to Blob. |
| * <pre> |
| * |
| * Example 1: |
| * |
| * @Lob @Basic(fetch=LAZY) |
| * @Column(name="REPORT") |
| * protected String report; |
| * |
| * Example 2: |
| * |
| * @Lob @Basic(fetch=LAZY) |
| * @Column(name="EMP_PIC", columnDefinition="BLOB NOT NULL") |
| * protected byte[] pic; |
| * |
| * </pre> |
