| Abstract | Component-based software design is a popular and effective approach to designing large systems. While components typically have well-defined interfaces, sequencing information---which calls must come in which order---is often not formally specified.This paper proposes using multiple finite statemachine (FSM) submodels to model the interface of a class. A submodel includes a subset of methods that, for example, implement a Java interface, or access some particular field. Each state-modifying method is represented as a state in the FSM, and transitions of the FSMs represent allow able pairs of consecutive methods. In addition, state-preserving methods are constrained to execute only under certain states.We have designed and implemented a system that includes static analyses to deduce illegal call sequences in a program, dynamic instrumentation techniques to extract models from execution runs, and a dynamic model checker that ensures that the code conforms to the model. Extracted models can serve as documentation; they can serve as constraints to be enforced by a static checker; they can be studied directly by developers to determine if the program is exhibiting unexpected behavior; or they can be used to determine the completeness of a test suite.Our system has been run on several large code bases, including the joeq virtual machine, the basic Java libraries, and the Java 2 Enterprise Edition library code. Our experience suggests that this approach yields useful information. |

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.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
