2. Approaches to Distribution

Let us now consider how distribution can be expressed in a statically typed object oriented system, with the purpose of supporting incremental development.

• The common approaches to distribution
  • Explicit distribution
  • Synchronization
    • Blocking
    • Locking
    • Penalties for incremental development
  • Message passing
• The Operation Metaphor
  • Operations as virtual threads of control
  • Generic operation interfaces
    • Scheduler
    • Initiator
    • Other operations
  • Genericity versus classification
  • Type nesting
  • Non determination
