Understanding the impact of language features on reusability

We present a conceptual model for helping us understand the nature of software reusability, particularly to help us understand how language features affect the reusability of software. The fundamental concept for our model is that of dependencies. We identify properties of dependencies between segments of code that are important to reusability. We validate our model by showing its application to well understood principles of reusability. We demonstrate that being able to describe these principles in a single framework allows us to gain a better understanding of reusability.
