scala - 在 Scala 中调用具有相同实例的多个函数

Question

有什么办法可以在 Scala 中实现以下目标

with new Car() {
     examineColor
     bargain(300)
     buy
}

代替

val c = new Car()
c.examineColor
c.bargain(300)
c.buy

Answer 1

这个怎么样:

scala> val c = new Car {
     |     examineColor
     |     bargain(300)
     |     buy
     | }

或者:

scala> { import c._
     |   examineColor
     |   bargain(300)
     |   buy
     | }
