어떻게 소프트웨어의 유연함을 성취 했을까 ?

Careful design

Configurable

Using software component

선택적 실행

변화종류 예상

설정에 따른

가변 & 불변 구분

기능 분리독립성 , 교환성

이식성

확장성

소프트웨어 제품 배포 이후에 ..

Pattern 1. Plug-InProblem

어떻게 소프트웨어 제품 배포 이후에 기능을 수정 및 추가 할 수 있을까 ?

Plug-In 인터페이스

( 인터페이스는 플러그인의 연결고리 )

배포된 이후에 기능이 개발되어 추가 가능 !!

기능 추가시 플랫폼은 영향 받지 않는다 .

Pattern 1. Plug-InSolution

완제품보다 기능을 밖으로 뺀 소프트웨어가 시장 진출이 빠르다 .

Pattern 1. Plug-InContext

어떻게 플러그인 INTERFACE 를 정의할까 ?

“ Android Platform ”

“ 구현된 Activity ”Interface

Pattern 1. Plug-InProblem

“ 구현된 Service ” . . .

“ Plug-In Contract ” 이런 약속으로 의존관계를 구성하겠다 .

Plug-In 의기능 (function) 들을알고 활용한다 .

Plug-In 을 활성화 , 중지 ,교환 , 소통

Pattern 1. Plug-InSolution

Plug-In ( 특정 Activity, Service) 은 재 사용될 수 있다 .

Pattern 1. Plug-InConsequences

Plug-In ( 특정 Activity, Service) 이 플랫폼에 통합되기 쉬어진다 .

안드로이드 App

Pattern 1. Plug-InConsequences

Plug-In Contract

Framework-Providing Platform 에 의해서Plug-In 이 이용되고 관리 된다 .

Ex) 안드로이드 Platform

Plug-In Contract 는 Plug-In 와 Framework-Providing Platform 의 관계를 정의

Plug-In 이 따라야할 추상클래스 (Definition) +Plug-In 을 관리할 인터페이스 (Framework) 를 규정
