Connections
Connected actors send each other Exit
signals and terminate together unless they are made :sticky
with trapExit
:
Actors.connect
— Functionconnect(lk::Link)
Create a connection between the calling actor and the actor represented by lk
.
Connected actors will send each other Exit
signals. A connected actor will exit with the signaled reason unless it is :normal
.
Note:
- An actor can be made
:sticky
withtrapExit
and then will not exit. - If this is called from the
Main
scope,lk
is
connected to the Actors._ROOT
actor.
Actors.disconnect
— Functiondisconnect(lk::Link)
Remove the connection between the calling actor and the actor represented by lk
.
Note: If this is called from the Main
scope, lk
is disconnected from the _ROOT
actor.
Actors.trapExit
— FunctiontrapExit(lk::Link=self(), mode=:sticky)
Change the mode of an actor.
A :sticky
actor does not exit if it receives an Exit
signal from a connected actor and does not propagate it further. Instead it reports the failure and saves a link to the failed actor.
See diag
for getting links to failed actors from a :sticky
actor.
