Description copied from interface: ByteOutput

关闭此流, 并执行与关闭相关的所有必要行为.

close() 不只是单纯的关闭操作: 在某些实现中, close() 可能触发额外的有意义动作, 例如:

• 刷新缓冲区或输出最终数据
• 发送或接收协议结束标志
• 写入校验、尾块或元数据
• 提交事务性状态
• 释放底层系统资源

正因为 close() 可能包含这些只能发生一次的行为, 所以此处 close() 设计为一次性操作，而非幂等操作. 若流已关闭, 重复调用 close() 属非法调用, 将抛出 AlreadyClosedException.
