--Software architectures enable large-scale software development. Component reuse and substitutability, two key aspects of large-scale development, must be planned for during software design. Object-oriented (OO) type theory supports reuse by structuring inter-component relationships and verifying those relationships through type checking in an architecture definition language (ADL). In this paper, we identify the issues and discuss the ramifications of applying OO type theory to the C2 architectural style. This work stems from a series of experiments that were conducted to investigate component reuse and substitutability in C2. We also discuss the limits of applicability of OO typing to C2 and how we addressed them in the C2 ADL.

“…To demonstrate this claim, we substituted SkyBlue with Amulet's one-way formula constraint solver [17]. This exercise required identifying, extracting, and recompiling the needed portion of Amulet, a task that was accomplished by a single developer in approximately 25 hours.…”

“…LayoutManager-6 had some of its constraints defined in SkyBlue and others in Amulet. Combining multiple constraint solvers in a single system has only recently been identified as a potentially useful approach to constraint man- agement [17], [32]. Integrating multiple constraint solvers in a single C2 component is certainly at a different level of granularity.…”

“…In a series of exercises, we were able to integrate several OTS components of various granularities into architectures that adhere to the rules of C2. This paper focuses on a subset of these exercises, in which we successfully integrated two externally developed UI constraint solvers into a C2 architecture: SkyBlue [32] and Amulet's oneway formula solver [17]. In doing so, we were able to create several constraint maintenance components in the C2 style, enabling the construction of a large family of applications.…”

Reuse of large-grain software components offers the potential for significant savings in application development cost and time. Successful reuse of components and component substitutability depends both on qualities of the components reused as well as the software context in which the reuse is attempted. Disciplined approaches to the structure and design of software applications offers the potential of providing a hospitable setting for such reuse. We present the results of a series of exercises designed to determine how well "off-the-shelf" constraint solvers could be reused in applications designed in accordance with the C2 software architectural style. The exercises involved the reuse of SkyBlue and Amulet's one-way formula constraint solver. We constructed numerous variations of a single application (thus an application family). The paper summarizes the style and presents the results from the exercises. The exercises were successful in a variety of dimensions; one conclusion is that the C2 style offers significant potential for the development of application families and that wider trials are warranted. 1 Index Terms-architectural styles, message-based architectures, application families, graphical user interfaces (GUIs), constraint management, component-based development.
