OOP + Actor Model Saturday, September 15, 12
“I thought of objects being like biological cells and/or individual
computers on a network, only able to communicate with messages” - Alan Kay, creator of Smalltalk, on the meaning of "object oriented programming" Saturday, September 15, 12
Active Objects Based on the Actor Model Saturday, September 15,
12
Saturday, September 15, 12
Saturday, September 15, 12
Actor Model •Actors are computational entities that can receive messages
•Each actor has a unique address •If you know an actor’s address, you can send it messages •Actors can create new actors Saturday, September 15, 12
I’m not the first to do Actor Model + OOP
