Automating Delegation in Class-Based Languages

Some designers of class-based object oriented languages choose not to support multiple inheritance. As a result, programmers often resort to ad hoc workarounds. The most common of these workarounds is delegation. Even delegation is tedious and error prone, however: We believe that language designers who choose against multiple inheritance should consider automating delegation in order to alleviate these problems. In this paper; we present Jamie, a language extension for Java that automates delegation. We also discuss the advantages and disadvantages of both delegation and automating it in a class-based programming language. Many of our observations are based on our experiences with implementing and using Jamie
