Actor model for golang.
This project aims to implement actor model from erlang to Go. It attempts to
add a concept of Pid which is universal identifier for actors.
Actor supports Call which is a syncronous method call. Cast which is
asyncronous method call ignoring all errors.
Actors can communicate with other actors using Call and Cast. Remote actors
are treated same as local actors.
This project is originally based on GLAM
package main
import (

)
type Phonebook struct {
cine.Actor
book map[string]int
}
func (p *Phonebook) Add(name string, number int) {
p.book[name] = number
}
func (p *Phonebook) Lookup(name string) (int, bool) {
result, ok := p.book[name]
return result, ok
}
func (p *Phonebook) Terminate(errReason error) {
}
func main() {
cine.Init("127.0.0.1:8000")
phonebook := Phonebook{cine.Actor{}, make(map[string]int)}
pid := cine.StartActor(&phonebook)
cine.Cast(pid, nil, (*Phonebook).Add, "Jane", 1234)
ret, _ := cine.Call(pid, (*Phonebook).Lookup, "Jane")
number := ret[0].(int)
glog.Infoln("number:", number)
// Out: number: 1234
}Preliminary benchmarks indicate about 5x overhead over vanilla channels. Do not use actors for call heavy operations.
