| void | clearUpdates() | 
| void | free()This method frees the  Blobobject and releases the resources that
 it holds. | 
| InputStream | getBinaryStream()Retrieves the  BLOBvalue designated by thisBlobinstance as a stream. | 
| InputStream | getBinaryStream(long pos,
               long length)Returns an  InputStreamobject that contains a partialBlobvalue,
 starting  with the byte specified by pos, which is length bytes in length. |

| byte[] | getBytes(long pos,
        int length)Retrieves all or part of the  BLOBvalue that thisBlobobject represents, as an array of bytes. | 
| boolean | isClosed() | 
| long | length()Returns the number of bytes in the  BLOBvalue designated
 by thisBlobobject. | 
| long | position(Blob pattern,

  patternbegins within theBLOBvalue that
 thisBlobobject represents. |

Blob object and releases the resources that
 it holds. The object is invalid once the free
 method is called.
 
 After free has been called, any attempt to invoke a
 method other than free will result in a SQLException
 being thrown.  If free is called multiple times, the subsequent
 calls to free are treated as a no-op.
