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;
