스티브 잡스(Steve jobs)가 정의한 객체지향 소프트웨어

Jeff Goodell: Would you explain, in simple terms, exactly what object-oriented software is?

객체 지향 소프트웨어가 무엇인지 간단하게 설명해 주시겠습니까?

Steve Jobs: Objects are like people. They’re living, breathing things that have knowledge inside them about how to do things and have memory inside them so they can remember things. And rather than interacting with them at a very low level, you interact with them at a very high level of abstraction, like we’re doing right here.

오브젝트는 사람과 같습니다. 마치 살아있고 숨쉬는것과 같이, 기억을 할 수 있고, 뭘 해야할지에 대한 지식이 있습니다. 매우 낮은 수준에서 상호 작용하는 것이 아니라, 여기에서하는 것처럼 매우 높은 수준의 추상화로 상호 작용할 수 있습니다.

Here’s an example: If I’m your laundry object, you can give me your dirty clothes and send me a message that says, “Can you get my clothes laundered, please.” I happen to know where the best laundry place in San Francisco is. And I speak English, and I have dollars in my pockets. So I go out and hail a taxicab and tell the driver to take me to this place in San Francisco. I go get your clothes laundered, I jump back in the cab, I get back here. I give you your clean clothes and say, “Here are your clean clothes.”

예를 들면 다음과 같습니다. 세탁물인 경우 더러운 옷을 주고 “옷을 세탁 할 수 있습니까?” 라는 메시지를 보낼 수 있습니다. 샌프란시스코 최고의 세탁 장소가 어디인지 알고 있습니다. 저는 말을 하고, 주머니에 달러가 있습니다. 그래서 나는 택시를 부르고 운전 기사에게 샌프란시스코의 이 장소로 데려가라고 지시합니다. 옷을 세탁하고 택시로 돌아 왔어요. 나는 당신에게 깨끗한 옷을주고 “깨끗한 옷이 있습니다”라고 말합니다.

You have no idea how I did that. You have no knowledge of the laundry place. Maybe you speak French, and you can’t even hail a taxi. You can’t pay for one, you don’t have dollars in your pocket. Yet I knew how to do all of that. And you didn’t have to know any of it. All that complexity was hidden inside of me, and we were able to interact at a very high level of abstraction. That’s what objects are. They encapsulate complexity, and the interfaces to that complexity are high level.

 여러분은 어떻게 내가 그걸 했는지 알수 없습니다. 그리고 세탁소와 관련된 장소에 대한 지식이 없습니다.  아마도 프랑스어를 할 수도 있고 택시를 부르지도 못할 수도 있고, 비요을 지불 할 수없고, 주머니에 달러가 없습니다. 그러나 나는 그 모든 것을 하는 방법을 알고있었습니다. 그리고 당신은 그것을 알 필요가 없습니다. 그 모든 복잡성은 내 안에 숨겨져 있었고, 우리는 매우 높은 수준의 추상화에서 상호 작용할 수 있었습니다. 그것이 바로 오브젝트입니다. 그것들은 복잡성을 캡슐화하고, 그 복잡성에 대한 인터페이스는 고수준입니다.
