| Abstract | Context-oriented programming can be regarded as a technique aiming for an improved (multi-dimensional) separation of concerns (MDSOC). The delMDSOC (virtual) machine model describes a common target platform for a range of high-level MDSOC approaches. As it is based only on the well-known concepts of objects, messages and delegation, it provides a means to express the semantics of context-oriented programming using these same notions as well. An approach based on structured operational semantics (SOS) exists, but it has a number of drawbacks, including its implicit representation of program state and the lack of a simulation mechanism. In this paper we introduce a graph-based semantics for context-oriented programming built on top of a concurrent actor-based semantics of delMDSOC. The semantics consists of a number of graph rewrite rules which can be applied to sample graphs using the AGG tool. This allows for the visual simulation of context-oriented programs, which we demonstrate by means of an example. |
