| Abstract | Information hiding controls which parts of a module are visible to different clients. This aids maintenance because hidden implementation details can be changed without affecting clients. The benefits of information hiding apply not only to code but also to other artifacts, such as specifications. In this demonstration we show how our client-aware checking (CAC) technique, which is implemented by our JML/ajmlc compiler and freely available online, use the privacy information in specifications to promote information hiding. We demonstrate the benefits of CAC over existing runtime assertion checkers (RACs) of contemporary interface specification languages. Client-aware checking allows runtime assertion checking and error reporting based solely on specifications visible to clients. This avoids exposing hidden implementation or specification details that cannot be understood by non-privileged clients. This demonstration will proceed by discussing the goals of the CAC technique by means of realistic examples. Attendees will mainly see JML specifications, including pre- and postconditions for methods. They will learn how to use the JML/ajmlc compiler, which also provides information hiding capabilities. In addition, they will learn how to use model fields to hide the actual field declarations in classes, and how model fields play an important role in achieving information hiding. We will conclude with pointers to ongoing work on design, implementation and runtime checking of Java programs with CAC-based JML/ajmlc. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
