包路径：io.vertx.core.buffer.Buffer
类名称：Buffer
方法名：appendInt

Buffer.appendInt介绍

[英]Appends the specified int to the end of the Buffer. The buffer will expand as necessary to accommodate any bytes written.

Returns a reference to this so multiple operations can be appended together.
[中]将指定的int追加到缓冲区的末尾。缓冲区将根据需要扩展以容纳写入的任何字节。
返回对此的引用，以便可以将多个操作附加在一起。
