| Abstract | Elements in OOP are classified under maximum five access modifiers which are: public, private, protected and etc. Although, they are useful to restrict the access to the object oriented elements, they are not as restricting as enough and there isnpsilat any approach to change or customize them and therefore, their definitions arenpsilat modifiable and are the same for all systems. Moreover, all access types to an object which are read, write, update and so on, can totally be granted or denied at the same time. So, itpsilas not possible to have a situation in which the permission of writing to an attribute is denied while reading the amount of it is granted. Furthermore, it is not possible for programmers to define new required access modifiers because of inflexibility, inextensibility and coarse granularity of current access modifiers. For example, defining two attributes in a class by different access rights on them is not possible. Besides, using current access modifiers we canpsilat limit the access of some methods of a class not only to another class but also to an attribute of their own classes. In this paper, we define expansive access modifier (EAM) which includes who (as a subject of an access) may request an access (read, write, etc.) to what element (as a target) as well as some additional control parameters. This approach is the solution without current drawbacks of access modifiers. |

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.
