/**
* 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>
*
* @see Basic
* @see ElementCollection
