本文整理了Java中org.glassfish.grizzly.Buffer.flip()方法的一些代码示例，展示了Buffer.flip()的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。Buffer.flip()方法的具体详情如下：
包路径：org.glassfish.grizzly.Buffer
类名称：Buffer
方法名：flip

Buffer.flip介绍

[英]Flips this buffer. The limit is set to the current position and then the position is set to zero. If the mark is defined then it is discarded.

After a sequence of channel-read or put operations, invoke this method to prepare for a sequence of channel-write or relative get operations. For example:

buf.put(magic);    // Prepend header 
in.read(buf);      // Read data into rest of buffer 
buf.flip();        // Flip buffer 
out.write(buf);    // Write header + data to channel

This method is often used in conjunction with the Buffer#compact method when transferring data from one place to another.
[中]翻转此缓冲区。将限制设置为当前位置，然后将该位置设置为零。如果定义了标记，则该标记将被丢弃。
在一系列通道读取或put操作之后，调用此方法以准备一系列通道写入或相对get操作。例如：

buf.put(magic);    // Prepend header 
in.read(buf);      // Read data into rest of buffer 
buf.flip();        // Flip buffer 
out.write(buf);    // Write header + data to channel

在将数据从一个地方传输到另一个地方时，此方法通常与缓冲区压缩方法结合使用。
