에 대한 별도의 인스턴스를 만들 필요가 없다. 참조값에 대한 클래스는 원래와 마찬가지로 작동
한다.
원래 컨테이너를 트레이트로 바꿈으로써 기존의 상속 관계는 두 클래스 인스턴스에서도 유효
하다. 예를 들어 매개변수화한 타입
class
C
[
T
]
와
class
D
[
T
]
가 있는데,
class
D
[
T
]
extends
C
[
T
]
였다고 하자. 그리고 그 둘을 모두 특화했다고 하자. 그러면 만들어진 코드는 개념적으로
다음과 비슷하다.
trait C
[
T
]
//
원래는
class C
[
T

class C

primitive

I wanted to learn C and C++, but it didn't click for me until I picked up an O'Reilly book. When I went on the O’Reilly platform, I was astonished to find all the books there, plus live events and sandboxes so you could play around with the technology.

I’ve been on the O’Reilly platform for more than eight years. I use a couple of learning platforms, but I'm on O'Reilly more than anybody else. When you're there, you start learning. I'm never disappointed.
Amir M.

I'm always learning. So when I got on to O'Reilly, I was like a kid in a candy store. There are playlists. There are answers. There's on-demand training. It's worth its weight in gold, in terms of what it allows me to do.
