Efficient Layered Method Execution in ContextAmber
Article No.: 5, Pages 1 - 6
Abstract
We present ContextAmber, a framework for context-oriented programming, in Amber Smalltalk, an implementation of the Smalltalk programming language that compiles to JavaScript. ContextAmber is implemented using metaprogramming facilities and supports global, object-wise, and scoped layer activation. Current COP implementations come at the expense of significantly reduced execution performance due to multiple partial method invocations and layer composition computations every time a layered method is invoked. ContextAmber can reduce this overhead by inlining partial methods, caching layer compositions, and caching inlined layered methods, resulting in a runtime overhead of about 5% in our vector graphics rendering benchmarks.

Method safety mechanism for asynchronous layer deactivation
Context-oriented programming (COP) enhances the modularity of context-dependent behavior in context-aware systems, as it provides modules to implement context-dependent behavior (layers) and composes them dynamically in a disciplined manner (layer ...
EventCJ: a context-oriented programming language with declarative event-based context transition
AOSD '11: Proceedings of the tenth international conference on Aspect-oriented software developmentThis paper proposes EventCJ, a context-oriented programming (COP) language that can modularly control layer activation based on user-defined events. In addition to defining context-specific behaviors by using existing COP constructs, the EventCJ ...
Featherweight EventCJ: a core calculus for a context-oriented language with event-based per-instance layer transition
COP '11: Proceedings of the 3rd ACM International Workshop on Context-Oriented ProgrammingWe propose Featherweight EventCJ, which is a small calculus for context-oriented languages with event-based per-instance layer controls like EventCJ. It extends ContextFJ with stores, labels and transitions for modeling the per-instance layer management,...
