Abstract

Component-based modelling is used as the basis of a number of approaches including Enterprise Architecture and System Architecture Design. Service Oriented Architecture (SOA) is a popular component-based approach but it has been criticised as not being suficiently flexible. A more flexible alternative is Event Driven Architecture (EDA) that can support Complex Event Processing. Dynamic reconfiguration of component behaviour is attractive because it allows an architecture to be extended and modified in situ without being taken off-line, updated and redeployed. This article shows how higher-order functions and reflection can support dynamic reconfiguration and how this approach is integrated with EDA. The approach is defined as patterns expressed in a component modelling language called LEAP and validated through a case study.
