The JCop language specification : Version 1.0, April 2012

Abstract

Das Verhalten von modernen Software-Anwendungen benötigt häufig Informationen über den Kontext ihrer Ausführung, z.B. die geografische Position, die Tageszeit oder die aktuelle Netzwerkbandbreite. Dennoch bieten heutige Programmiersprachen nur wenig Unterstützung für die Repräsentation kontextspezifischen Verhaltens. Kontextorientiertes Programmieren ist ein Ansatz, der die explizite Modularisierung und Laufzeitaktivierung von kontextspezifischem Verhalten auf der Ebene von Programmiersprachkonstrukten ermöglicht. Die bisherigen Umsetzungen von kontextorientiertem Programmieren schränken jedoch die Kontrolle der Laufzeitaktivierungen solches kontextspezifischen Verhaltens ein. Daraus folgt eine Einschränkung der Anwendungsbereiche für kontextorientiertes Programmieren, unter anderem für solche Domänen, in denen Programme sehr häufig kontextabhängiges Verhalten bereitstellen, z.B. ereignisbasierte, mobile und dienstorientierte Systeme. Die Programmiersprache JCop erweitert Java um Sprachkonstrukte für kontextorientieres Programmieren und bietet zusätzlich eine domänenspezifische Aspektsprach an, mit deren Hilfe Laufzeitadaptionen deklarativ spezifiziert werden können. Die Kernkonzepte von JCop wurden bereits in mehrern Publikationen vorgestellt, dieser Bericht enthält nun eine umfassende Sprachspezifikation von JCop.

Program behavior that relies on contextual information, such as physical location or network accessibility, is common in today's applications, yet its representation is not sufficiently supported by programming languages. With context-oriented programming (COP), such context-dependent behavioral variations can be explicitly modularized and dynamically activated. In general, COP could be used to manage any context-specific behavior. However, its contemporary realizations limit the control of dynamic adaptation. This, in turn, limits the interaction of COP's adaptation mechanisms with widely used architectures, such as event-based, mobile, and distributed programming. The JCop programming language extends Java with language constructs for context-oriented programming and additionally provides a domain-specific aspect language for declarative control over runtime adaptations. As a result, these redesigned implementations are more concise and better modularized than their counterparts using plain COP. JCop's main features have been described in our previous publications. However, a complete language specification has not been presented so far. This report presents the entire JCop language including the syntax and semantics of its new language constructs.
