question: @ Override public LogSeqNum writeToLog ( ) { List < Constant > rec = buildRecord ( ) ; return logMgr . append ( rec . toArray ( new Constant [ rec . size ( ) ] ) ) ; }
target:  Writes a setval record to the log. This log record contains the SQL type corresponding to the value as the operator ID, followed by the transaction ID, the filename, block number, and offset of the modified block, and the previous integer value at that offset.
