Abstract

It is difficult to assemble independently developed software components because of discrepancies between their interfaces. In order to resolve such problem, we propose a new component model, Active Binding Technology, in which each component has its own independently-defined interface for service request that is revealed in its metadata, instead of passively following the interface of a service-providing component. This model Includes the use of the glue component, an interface mediating place, whose template code is automatically generated by reading in the metadata of the components to be combined. We also propose a runtime framework that holds the pool of component instances, completes the assembly of components in the manner of dependency injection, and performs middleware services and real-time system monitoring through glue components. In order to test the practical value of Active Binding Technology, we have made a tool, which supports the development and assembly of Active Binding components.

독립적으로 개발된 상용 컴포넌트들을 소스 코드 수정 없이 조립하여 재사용하기 위해서는 컴포넌트간 인터페이스 불일치 문제를 해결해야 한다. 본 논문에서는 이러한 문제를 해결하기 위한 새로운 컴포넌트 모델 및 조립 방법을 제안한다. 제안한 컴포넌트 모델은 각 컴포넌트가 서비스를 제공하는 하위 컴포넌트의 인터페이스에 의존하는 대신 서비스 요청에 관한 인터페이스를 독자적으로 정의하여 내장하고 이를 메타데이타로 노출한다. 조립 시에는 컴포넌트들의 요청 및 서비스 제공 인터페이스에 대한 메타데이타를 읽어 글루 컴포넌트 템플릿 코드를 자동 생성하여 인터페이스 정합에 필요한 중재 코드를 삽입하는 구조이다. 또 프레임워크에서 컴포넌트들에 대한 인스턴스를 관리하고 런타임시 의존성 주입 방식으로 조립을 수행하며, 글루 컴포넌트를 미들웨어 서비스 포인트 및 실시간 모니터링 포인트로 활용하는 방안도 제안한다. 이와 한께 본 논문은 제안한 컴포넌트 모델에 따르는 컴포넌트를 개발하고 조림하는 도구를 구현하여, 실용 가능성을 입증하였다.
