Using document-oriented GUIs in dynamic software product lines

Abstract

Dynamic Software Product Line (DSPL) Engineering has gained interest through its promise of being able to unify software adaptation whereby software adaptation can be realised at compile time and runtime. While previous work has enabled program logic adaptation by the use of language extensions and platform support, little attention has been placed on Graphical User Interface (GUI) variability. Different design patterns including the Model View Controller are commonly used in GUI implementation, with GUI documents being used for declaring the GUI. To handle dynamic GUI variability currently, the developer needs to implement GUI refinements using multiple techniques. This paper proposes a solution for dealing with GUI document variability, statically and dynamically, in a unified way. In our approach, we currently use a compile time method for producing GUI variants, and code transformations to handle these variants within the application at runtime. To avoid GUI duplicates, only GUI variants that are unique, and related to a valid product configuration, are produced. To validate our approach, we implemented tool support to enable this for Android based applications.

Formal Verification for Feature-Based Composition of Workflows

“…Dynamic feature binding and GUI applications Kramer et al [21] have contributed an approach that supports both static and runtime feature binding of GUIs based on Dynamic SPLs (DSPLs [17]). We also support runtime feature binding of executable workflows which include GUI forms.…”

“…We also support runtime feature binding of executable workflows which include GUI forms. Kramer et al [21] discuss certain challenges including keeping the components of Model-View-Controller (MVC) architectures consistent in the presence of variability. In this regard, note that in Section 4 we demonstrate that we can automatically solve this consistency problem with a dependent record type.…”

Taking advantage of the software product line paradigm to generate customized user interfaces for decision-making processes: a case study on university employability

“…DSPLs provide a useful paradigm for adapting code at run-time, obtaining adaptive GUIs. Kramer et al (2013) proposed document-oriented GUIs with run-time variations through XML documents (Kramer et al, 2013). This context-adaptable feature has also been achieved by Sboui, Ayed & Alimi (2018), by developing a mobile application that is also runtime adaptable through MBUID models and reusable artifacts.…”
