Uma arquitetura de software para reuso de componentes
Abstract
The paper addresses the software reuse, more specifically the problem of developing applications from pre-existing software components. These components have concrete and template methods which offer a specific functionality to be used in the application development. This paper presents a technique that allows the application developer to specify the expected relation between the application classes and a set of pre-existing components. In this relation, we can identify two kinds of reuse: use and implementation. The "use" contract establishes the rules for the use of component methods by application methods. The "implementation" contract establishes the rules for the implementation of abstract methods of a component. In order to allow the implementation of the contracts, a integration architecture is proposed, formed by components, application classes and integration classes. The integration classes are specified as design patterns. The paper describes the development of applications that use components and shows the way the integration architecture must be constructed.
