Refactoring Behavior: SDM

1. Bind method > (Hidden) Cast target

2. Bind container > Link Navigation

3. Bind stub > Link Navigation

4. Bind superclass > Link Navigation

5. Remove method from container

6. Add method to superclass

1. SDM could only be drawn in Fujabaß Industry Requires Commercial Support

2. Fujaba code generator assumes target repositorycomplies to Fujaba API.ß XMI + JMI + EMF + … desirable

Problem: Vendor Lock-In

9/24

1. SDM could only be drawn in Fujabaß Solution: UML Profile for SDM

2. Fujaba code generator assumes target repositorycomplies to Fujaba API.ß Solution: Pluggable Code Templates

Solution: Reflective MDA Light

ÿ Poseidon Plugin– Extra menu item for

launching transformation

23/24

Conclusions (1/2)1. Now transformation writers can…ß Create visual model transformations in Magicdraw, Together,

Objecteering, Poseidon, …ß Execute them on JMI repositories (opt: CASE tool plugins)

2. Now, Fujaba can…ß be migrated to MDR

3. Now, other CASE tool vendors can…ß Provide a plugin for enhanced visualization (cfr. nesting)

24/24

Conclusions (2/2)ÿ Lessons Learned

– MDA Light¸ UML Profiles: adequate if MM close to UML¸ Code Templates: reuse problems

– Graph Rewriting¸Convenient for specifying Refactorings

ÿ Future Work– EMF support… if necessary, solve reuse problems with stepwise refinement– Model Refinement & Weaving Case Studies– Compare to (and align with) ATL
