Kilim templates

• Description of component construction/intializatio
  n mechanisms
• should be non intrusive (to be used for existing
  platform)
• A Kilim model reminder
• Providers and dependancies
• Abstraction of mechanisms for object construction
  (obtaining a reference) Constructors, Factory
  methods, lookup methods for repositories
• Dependancies induced by methods arguments,
• Transformer and triggers
• Abstraction of mechanisms for object
  initialization (triggered just after creation)

The model through an example (1)

• Build an application
• Construction captured by implementation ctors
  and setters
• Launcher (main for ex.)

Conclusion

• Kilim operational (XML parser, run-time,
  viewers and other helpers)
• used internally for building rather large
  industrial softwares
• future work
• introduction of dynamic reconfiguration
  mechanisms
• bind, unbind
• integration of distribution
• extension to C and C
• generation of compiled launchers
