DiSL

DiSL is a domain-specific language for Java bytecode instrumentation developed in cooperation between University of Lugano, Charles University in Prague and Shanghai Jiao Tong University.

DiSL is inspired by AOP, but in contrast to mainstream AOP languages, it features an open join point model where any region of bytecodes can be selected as a join point (i.e., code location to be instrumented). DiSL reconciles high-level language constructs resulting in concise instrumentations, high expressiveness, and efficiency of the inserted instrumentation code. Thanks to the pointcut/advice model adopted by DiSL, instrumentations are similarly compact as aspects written in AspectJ. However, in contrast to AspectJ, DiSL does not restrict the code locations that can be instrumented, and the code generated by DiSL avoids expensive operations (such as object allocations that are not visible to the programmer). Furthermore, DiSL supports instrumentations with complete bytecode coverage out-of-the-box and avoids structural modifications of classes that would be visible through reflection and could break the instrumented code.
