| Abstract | However, a single collaboration diagram is usually not expressive enough to model complex operations performing several modifications at different parts of the overall object structure. Such series of modifications need several collaboration diagrams to be modeled. In addition, there may be different situations where certain collaboration diagrams should be executed and others not. Thus, we need additional control structures to control the execution of collaboration diagrams. In our approach we combine collaboration diagrams with statecharts and activity diagrams for this purpose. This means, instead of just pseudo code, any state or activity may contain a collaboration diagram modeling the do-action of this step.Figure 1 illustrates the main concepts of Fujaba. Fujaba uses a combination of statecharts and collaboration diagrams to model the behavior of active classes. A combination of activity diagrams and collaboration diagrams models the bodies of complex methods. This integration of class diagrams and UML behavior diagrams enables Fujaba to perform a lot of static analysis work facilitating the creation of a consistent overall specification. In addition, it turns these UML diagrams into a powerful visual programming language and allows to cover the generation of complete application code. During testing and maintenance the code of an application may be changed on the fly, e.g. to fix small problems. Some application parts like the graphical user interface or complex mathematical computations may be developed with other tools. In cooperative (distributed) software development projects some developers may want to use Fujaba, others may not. Code of different developers may be merged by a version management tool. There might already exist a large application and one wants to use Fujaba only for new parts. One may want to do a global search-and-replace to change some text phrases. One may temporarily violate syntactic code structures while she or he restructures some code. For all these reasons, Fujaba aims to provide not just code generation but also the recovery of UML diagrams from Java code. One may analyse (parts of) the application code, recover the corresponding UML diagram (parts), modify these diagram (parts), and generate new code (into the remaining application code). So far, this works reasonable for class diagrams and to some extend for the combination of activity and collaboration diagrams. For statecharts this is under development.The next chapters outline the (forward engineering) capabilities of Fujaba with the help of an example session. |

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.
