## Annotation Type Lob

-     @Target(value={METHOD,FIELD})
      @Retention(value=RUNTIME)
      public @interface Lob

  Specifies that a persistent property or field should be persisted as a large object to a database-supported large object type.

  Portable applications should use the `Lob` annotation when mapping to a database Lob type. The `Lob` annotation may be used in conjunction with the `Basic` annotation or the `ElementCollection` annotation when the element collection value is of basic type. A `Lob` may be either a binary or character type.

  The `Lob` 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")
         protected String report;

         Example 2:

         @Lob @Basic(fetch=LAZY)
         @Column(name="EMP_PIC", columnDefinition="BLOB NOT NULL")
         protected byte[] pic;
