Featherweight generic confinement

Existing approaches to object encapsulation either rely on ad hoc syntactic restrictions or require the use of specialised type systems. Syntactic restrictions are difficult to scale and to prove correct, while specialised type systems require extensive changes to programming languages. We demonstrate that confinement can be enforced cheaply in Featherweight Generic Java, with no essential chan...

Generic Ownership: Practical Alias Control in Object-Oriented Programming Languages

Modern object-oriented languages support many techniques that simplify the work of a programmer. Among them is type genericity — an ability to create generic descriptions of algorithms and object structures that will be automatically specialised by supplying type information at run time. On the other hand, object-oriented technologies still suffer from bad effects of aliasing— a case of many ob...

Featherweight Ownership and Immutability Generic Java - Technical Report Yoav

1 Introduction This technical report contains proofs that were omitted from our paper entitled " Ownership and Immutability in Generic Java ". Please read the paper first, and only then proceed to reading this technical report, because this technical report is not self contained. We only include a summary of the syntax (Fig. 1), subtyping rules (Fig. 2), expression typing rules (Fig. 3), and re...

Welterweight Java

This paper presents Welterweight Java (WJ), a new minimal core Java calculus intended to be a suitable starting point for investigations in the semantics of Java-like programs. To this end, WJ adds a few extra pounds to Featherweight Java. WJ is imperative and stateful, which is a frequent extension of Featherweight Java. To account for the importance of concurrency, WJ models Java’s thread-bas...
