Problem

• Design concerns graphical element and movement
  tracking
• Dominant decomposition (OOP classes)
• Crosscutting concerns (scattered out across the
  system)

3
AOP Solution with AspectJ

• AOP elements
• Joint point model
• Means of identifying
• joint points
• Means of specifying behaviour at joint points
• Encapsulation unit
• Method of attachment of units to a program

4
AOP and Components

• 4S for successful separation
• 1. Simultaneous coexisting of different
  decompositions (implementations)
• 2. Self-contained understanding of each module
  in isolation
• 3. Symmetric composing of the aspects and
  modules
• 4. Spontaneous identify and encapsulate new
  concerns and modules
