XML unique renaming of Java source.

摘要

In order to assist in accurate Java software maintenance and further development, we present a flexible way in which a data design model extracted from Java programs can remain unified with the source code. Each entity declaration and reference in the Java program is assigned a global UID (unique identifier) based on its name and declaration context. The UID serves as a key by which its original declaration and other references can be found, and more importantly, by which facts about the entity can be stored and retrieved from the design model. While it is possible to generate the unique names in an ad hoc manner, we show how to generate them using a combination of source transformations and design model inferences.; UIDs are attached to each declaration and reference in the source code using XML markup, so that both the UIDs and the original source text are available in the renamed source program. The resulting uniquely renamed source code makes it convenient and efficient to do further business logic and technical analysis that crosses the boundary between the source code and its design model. Analysis and transformation of source and analysis and transformation of the design model can each be carried out independently without losing the connection to the other. We demonstrate this with an example application to Java library migration.
