## Template Method 패턴이란?

![What is Template Method](https://554043693-files.gitbook.io/~/files/v0/b/gitbook-legacy-files/o/assets%2F-MSm3cZika9wPcLt2w9B%2Fsync%2F713f9cea6a4d7880f6c389d9657b8038a2c304a1.png?generation=1623575374208732\&alt=media)

## Template Method 패턴의 아키텍처

* 훅(hook) 메서드란?
  * 슈퍼 클래스에서 디폴트 기능을 정의해두거나 비워뒀다가 서브 클래스에서 선택적으로 재정의 할 수 있도록 만들어 둔 메서드
  * 서브 클래스에서 추상 메서드를 구현하거나, 훅 메서드를 재정의하는 방법을 이용하여 기능의 일부를 확장
