“…There are several alternative programming languages and implementation mechanisms that can be adopted to express behavioral patterns and their related sub-concerns. We have extensively studied the shortcomings of the current languages for this matter [7][8][9][10]. In this section, we summarize our observations.…”

“…There are various proposals such as [4] to support programmable join point models, which are mainly limited to Java as the base language. As we studied in [8,10], supporting a single base language reduces the modularity of implementations when data is provided by various sources, for example multi-language base software.…”

“…Although event modules significantly improve upon current OO and AO modularization mechanisms to implement event processing applications [8][9][10], they come with some shortcomings. First, the instantiation and destruction strategies of event modules are largely similar to the ones offered by the AO languages with pointcutbased instantiation strategy.…”

Nowadays, detecting emergent behavioral patterns in the environment, representing and manipulating them become the main focus of many software systems such as traffic monitoring systems, runtime verification techniques and self-adaptive systems. In this paper, we discuss the need for dedicated linguistic constructs to modularly represent emergent behavioral patterns and their lifetime semantics. We explain the shortcomings of current languages with this regard. Inspired from the evolution of procedural languages to object-oriented and aspect-oriented languages, we explain the concept of event-based modularization, which can be regarded as the successor of the aspect-oriented modularization for representing emergent behavioral patterns and their lifetime semantics. We report on our work on event modules and their successor gummy modules, which facilitate representing behavioral patterns as a holistic module that encapsulates its lifetime semantics.

“…ServalCJ integrates such event-based mechanisms with dynamic activation of layers in COP. However, a more complex mechanism of event composition such as that proposed in [23,24] is currently not supported by the event model in ServalCJ.…”

Context-oriented programming (COP) languages modularize contextdependent behaviors in multiple classes into layers. These languages have layer activation mechanisms so that the behaviors in layers take effect on a particular unit of computation during a particular period of time. Existing COP languages have different layer activation mechanisms, and each of them has its own advantages. However, because these mechanisms interfere with each other in terms of extent (time duration) and scope (a set of units of computations) of activation, it is not trivial to combine them into a single language. We propose a generalized layer activation mechanism based on contexts and subscribers to implement the different activation mechanisms in existing COP languages in a single COP language called ServalCJ. Contexts specify the extent of activation through temporal logic terms, and subscribers specify the scope of activation through operators provided by the language. We implement a compiler of ServalCJ, and demonstrate its expressiveness by writing a couple of application programs.

“…The software construction is achieved through the composition of these event modules, where an event module can be composed using input (events received) and output (events published) interfaces. EventReactor [10,31,32] provides a set of language constructs to implement the event composition model. The proposal can be implemented for multi languages like Java and C. Similarly to JavaMop, patterns in EventReactor are expressed in a user-defined and potentially Turing complete language, but these patterns are not first-class values, reusable, and composable.…”

Artículo de publicación ISIStateful aspects can react to the trace of a program execution; they can support modular implementations of several crosscutting concerns like error detection, security, event handling, and debugging. However, most proposed stateful aspect languages have specifically been tailored to address a particular concern. Indeed, most of these languages differ in their pattern languages and semantics. As a consequence, developers need to tweak aspect definitions in contortive ways or create new specialized stateful aspect languages altogether if their specific needs are not supported. In this paper, we describe ESA, an expressive stateful aspect language, in which the pattern language is Turing-complete and patterns themselves are reusable, composable first-class values. In addition, the core semantic elements of every aspect in ESA areopen to customization. We describe ESA in a typed functional language. We use this description to develop a concrete and practical implementation of ESA for JavaScript. With this implementation, we illustrate the expressiveness of ESA in action with examples of diverse scenarios and expressing semantics of existing stateful aspect languages
