JSR-275 - Units and Measures for Java 7 - draft terminates soon
Friday 6 July 2007
I really interested in what it would be? And how it would be implemented?
This is what they say:
"Java developers who work with physical quantities (such as developers in the scientific, engineering, medical, and manufacturing domains) need to be able to handle measurements of these quantities in their programs. Inadequate models of physical measurements can lead to significant programmatic
errors. In particular, the practice of modeling a measure as a simple number with no regard to the units it represents creates fragile code. Another developer or another part of the code may misinterpret the number as representing a different unit of measurement. For example, it may be unclear whether a person's weight is expressed in pounds, kilograms, or stones.
Developers must either use inadequate models of measurements, or must create their own solutions. A common solution can be safer and can save development time for domain-specific work. This JSR proposes to establish safe and useful methods for modeling physical quantities."
JSR-275 "Measures and Units" Early Draft Public Review terminates soon (July 8). Your comments/feedback are important to us (the latest version 0.8 is available here).
The JSR-275 should be a major enhancement for Java 7 by providing "strong" typing (through class parameterization) and easy internationalization of Java programs (preventing conversion errors). The reference implementation is provided by the JScience project under BSD License.
Let's wait and will take a look when all will be done.
