| Abstract | Modern IDEs for object-oriented languages like Java provide support for a basic set of simple automated refactorings whose behaviour is easy to describe intuitively. It is, however, surprisingly difficult to specify their behaviour in detail. In particular, the popular precondition-based approach tends to produce somewhat unwieldy descriptions if advanced features of the object language are taken into account. This has resulted in refactoring implementations that are complex, hard to understand, and even harder to maintain, yet these implementations themselves are the only precise "specification" of many refactorings. We have in past work advocated a different approach based on several complementary notions of dependencies that guide the implementation, and on the concept of microrefactorings that structure it. We show in this work that these concepts are powerful enough to provide high-level specifications of many of the refactorings implemented in Eclipse. These specifications are precise enough to serve as the basis of a clean-room reimplementation of these refactorings that is very compact, yet matches Eclipse's for features and outperforms it in terms of correctness. |

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.
