Nodejs的io中io.sockets.adapter.rooms在哪里？

Question

/sf/answers/470914811/

简短的回答：
io.sockets.adapter.rooms

我分析了io：

如该答案所示，io 的套接字输出部分包含以下内容：

sockets: 
   { manager: [Circular],
     name: '',
     sockets: { '210837319844898486': [Object] },
     auth: false,
     flags: { endpoint: '', exceptions: [] },
     _events: { connection: [Function] } },

哪儿是adapter？哪里有rooms？

如何从 的输出中找出适配器和房间io？
