Purpose
The power of objects lies in the flexibility of their interconnection structure. But this flexibility comes at a cost. Because an object can be modified via any alias, object-oriented programs are hard to understand, maintain, and analyse. Aliasing makes objects depend on their environment in unpredictable ways, breaking the encapsulation necessary for reliable software components, making it difficult to reason about and optimise programs, obscuring the flow of information between objects, and introducing security problems.
Aliasing is a fundamental difficulty, but we accept its presence. Instead we seek techniques for describing, reasoning about, restricting, analysing, and preventing the connections between objects and/or the flow of information between them. Promising approaches to these problems are based on ownership, confinement, information flow, sharing control, escape analysis, argument independence, read-only references, effects systems, and access control mechanisms.
The workshop will generally address the question how to manage interconnected object structures in the presence of aliasing. In particular, we will consider the following issues (among others):
- models, type and other formal systems, programming language, separation logic, mechanisms, analysis and design techniques, patterns, tools and notations for expressing object ownership, aliasing, confinement, uniqueness, and/or information flow.
- optimisation techniques, analysis algorithms, libraries, applications, tools, and novel approaches exploiting object ownership, aliasing, confinement, uniqueness, and/or information flow.
- empirical studies of programs or experience reports from programming systems designed with these issues in mind
- novel applications of aliasing management techniques such as ownership types, ownership domains, confined types, region types, and uniqueness.
