Event-driven programming with EScala
Lucas Satabin, Mira Mezini · 2011
EScala is an extension of Scala with support for declarative event-driven programming. It provides mechanisms for declarative definition of events and employs aspect-oriented techniques for exposing implicitly existing events, which reduces the need for explicit triggering of events. EScala provides a conservative integration of declarative events into an object-oriented language. Events are declared as attributes of objects and are subject to inheritance and subtype polymorphism. The language fully preserves encapsulation of objects and modular compilation of classes. Designs based on declarative events are as efficient as conventional event-driven designs.
