Spoon

Abstract

This paper presents Spoon and its AOP extension. Spoon is a pure Java 5 framework for implementing source-level and annotation-driven program transformations. It aims to be a powerful tool to build and integrate middleware. Spoon allows for the definition of program processors and annotation processors that use Compile-Time reflection, which is achieved with an extension of Sun's APT. In particular, Spoon provides an AOP extension under the form of a set of annotation processors. With Spoon, it is possible to do comprehensive and efficient AOP in pure Java, without relying on any specific language or IDE support.
