Presentation Outline
• Project Products
– We have developed a tool called DAJ (Demeter AspectJ)
that adds traversals to AspectJ.
– DAJ
• Input: AspectJ program, extended with files containing traversal
specifications.
• Output: Compiled AspectJ program where the traversals have been
added using introductions.
• Research Context Diagram
– DAJ depends on the availability of AspectJ. We use
AspectJ to extend AspectJ but without modifying the
AspectJ compiler !!! This is possible thanks to AspectJ.

Presentation Outline (cont)
• OEP Architecture Requirements
– A project that uses Java and uses a complex UML class
diagram in which you program many object collaborations
that encode traversal-related concerns.
• Required OEP Project Products
– We need embedded system source code that uses object
collaborations that encode traversal-related concerns.
