/**
|
||
|
|
* 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.
|
||
|
|

|
* Example 1:
|
||
|
|
*
|
||
|
|
* @Lob @Basic(fetch=LAZY)
|

|
* @Column(name="REPORT")
