Style #28
Similar to the letterbox style, but where the 'things' have independent threads of execution.
Constraints:
-
The larger problem is decomposed into 'things' that make sense for the problem domain
-
Each 'thing' has a queue meant for other \textit{things} to place messages in it
-
Each 'thing' is a capsule of data that exposes only its ability to receive messages via the queue
-
Each 'thing' has its own thread of execution independent of the others.
Possible names:
- Free agents
- Active letterbox
- Actors
