Changes the Actor's behavior to become the new 'Procedure' handler.
Changes the Actor's behavior to become the new 'Procedure' handler. This method acts upon the behavior stack as follows:
discardOld = true
it will replace the top element (i.e. the current behavior)discardOld = false
it will keep the current behavior and push the given one atopThe default of replacing the current behavior on the stack has been chosen to avoid memory
leaks in case client code is written without consulting this documentation first (i.e.
always pushing new behaviors and never issuing an unbecome()
)

Defines the inactivity timeout after which the sending of a akka.actor.ReceiveTimeout message is triggered.
Defines the inactivity timeout after which the sending of a akka.actor.ReceiveTimeout message is triggered. When specified, the receive function should be able to handle a akka.actor.ReceiveTimeout message. 1 millisecond is the minimum supported timeout.
Please note that the receive timeout might fire and enqueue the ReceiveTimeout
message right after
another message was enqueued; hence it is not guaranteed that upon reception of the receive
timeout there must have been an idle period beforehand as configured via this method.
Once set, the receive timeout stays in effect (i.e. continues firing repeatedly after inactivity
periods). Pass in Duration.Undefined
to switch off this feature.
Messages marked with NotInfluenceReceiveTimeout will not reset the timer. This can be useful when
ReceiveTimeout
should be fired by external inactivity but not influenced by internal activity,
e.g. scheduled tick messages.
