Remarks

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:

<blockquote>

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

</blockquote>

This method is often used in conjunction with the java.nio.ByteBuffer#compact compact method when transferring data from one place to another.
