Resumo


Uma abordagem para extensão de frameworks baseada em um novo conceito, denominado Extension Join Points (EJPs), tem sido proposta anteriormente. EJPs possibilitam a extensão sistemática de frameworks, através do uso de aspectos de variabilidade e integração. Neste artigo, nós mostramos como os EJPs podem ser implementados usando os mecanismos da linguagem AspectJ. Para avaliar a utilidade dos EJPs no processo de extensão de frameworks, nós os utilizamos no desenvolvimento de 3 frameworks OO de diferentes domínios. Como um resultado de nossos estudos de caso, nós apresentamos: (i) uma categorização inicial de diferentes tipos de contratos entre frameworks, EJPs e aspectos, os quais podem ser implementados em AspectJ; e (ii) um conjunto de lições aprendidas quando especificando os EJPs.
