Object-oriented programming was supposed to unify the perspectives of the programmer and the end user in computer code: a boon both to usability and program comprehension. While objects capture structure well, they fail to capture system action. DCI is a vision to capture the end user cognitive model of roles and interactions between them.

Functions often depend on particular behavioral characteristics (“features”) of code they invoke. For example, thread-safe code must invoke only thread-safe code if it is to remain thread-safe, and exception-safe code must invoke only exception-safe code. This paper describes a technique that enables the specification of arbitrary combinations of user-defined code features on a per-function basis and that detects violations of feature constraints during compilation. The technique applies to member functions (both nonvirtual and virtual), non-member functions, and function templates; operators are excluded.

While the Java VM shields most developers from having to think about the memory-management aspects their Java objects, the VM does not completely manage other types of resources automatically, says Gwyn Fisher, CTO of Klocwork in this interview with Artima. Great Java developers learn to understand exactly what the JVM does, and does not do, for their objects.
