org.apache.derby.io.StorageRandomAccessFile.seek()
Set the file pointer. It may be moved beyond the end of the file, but this does not change the length of the file. The length of the file is not changed until data is actually written.. @param newFilePointer the new file pointer, measured in bytes from the beginning of the file. @exception IOException - if newFilePointer is less than 0 or an I/O error occurs.
