Event-based Context-Oriented Programming

We propose event-based context-oriented programming, and design and implement EventCJ, an event-based extension to ContextJ. Its design stems from our observation that, in many context-aware applications, context changes are triggered by external events. Thus, in addition to the current COP language mechanisms, namely the one to activate/deactivate layers in accordance with a flow of control in programs, and the one to dispatch method calls to partial methods on active layers, we propose a mechanism to declaratively specify how the receiver of events changes its active contexts. EventCJ can declare events that trigger context transitions, and context transition rules that define how each instance’s context changes when it receives a specific event.
