javax.sql.rowset.serial.SerialBlob
A serialized mapping in the Java programming language of an SQL BLOB value.
The SerialBlob class provides a constructor for creating an instance from a Blob object. Note that the Blob object should have brought the SQL BLOB value's data over to the client before a SerialBlob object is constructed from it. The data of an SQL BLOB value can be materialized on the client as an array of bytes (using the method Blob.getBytes) or as a stream of uninterpreted bytes (using the method Blob.getBinaryStream).
SerialBlob methods make it possible to make a copy of a SerialBlob object as an array of bytes or as a stream. They also make it possible to locate a given pattern of bytes or a Blob object within a SerialBlob object and to update or truncate a Blob object.
Thread safety

A SerialBlob is not safe for use by multiple concurrent threads. If a SerialBlob is to be used by more than one thread then access to the SerialBlob should be controlled by appropriate synchronization. @author Jonathan Bruce
