ReLAx: Implementing KALA over the Reflex AOP Kernel
Abstract
Domain-specific aspect languages (DSALs) bring the well-known advantages of domain specificity to the level of aspect code. However, DSALs incur the significant cost of implementing or extending a language processor or weaver. This raises the necessity of an appropriate infrastructure for DSALs. This paper illustrates how the Reflex kernel for multi-language AOP allows for the definition of DSALs, by considering the implementation of a DSAL for advanced transaction management, KALA. We detail the implementation of KALA in Reflex, illustrating the ease of implementation of runtime semantics, syntax, and language translation
