Rewriting Strategies in Java

In any language designed to express transformations, the notion of rewrite rule is a key feature. Its conciseness as well as its strong theoretical foundations are essential. The notion of strategy is complementary: this describes how rules are applied. In this paper, we show how a high-level strategy language can be implemented in a Java setting. We present the integration of the visitor combinator design pattern into Tom. This corresponds to an interpreter for strategy expressions. To be more efficient, we present a compilation method based on bytecode specialization. This low-level transformation is expressed in Tom itself, using rules and strategies.
