Interface 类
- 继承自: <EventEmitter>
readline.Interface 类的实例是使用 readline.createInterface() 方法构造的。
每个实例都与单个 input 可读流和单个 output 可写流相关联。
output 流用于打印到达并从 input 流中读取的用户输入的提示。
- Extends: <EventEmitter>
Instances of the readline.Interface class are constructed using the
readline.createInterface() method. Every instance is associated with a
single input Readable stream and a single output Writable stream.
The output stream is used to print prompts for user input that arrives on,
and is read from, the input stream.
