Abstract

Hyper/J supports a new approach to constructing, integrating and evolving software, called multi-dimensional separation of concerns. Developers can decompose and organize code and other artifacts according to multiple, arbitrary criteria (concerns) simultaneously—even after the software has been implemented—and synthesize or integrate the pieces into larger-scale components and systems. Hyper/J facilitates several common development and evolution activities non-invasively, including: adaptation and customization, mix-and-match of features, reconciliation and integration of multiple domain models, reuse, product line management, extraction or replacement of existing parts of software, and on-demand remodularization. Hyper/J works with standard Java software, not requiring special compilers or environments. This demonstration will show it in action in a number of software engineering scenarios at different stages of the software lifecycle.
