Hi all,
I am trying to send a message to an actorRef, 5 seconds apart, for
each line in a file. Here's how I'm attempting to do this:
val filename = "conf/my_file.json"
val lines = scala.io.Source.fromFile(filename).getLines.toList
for (line <- lines) {
Akka.system.scheduler.scheduleOnce(5 seconds) {
testStream ! Message(line)
}
}
The whole for loop runs immediately you are scheduling all lines to be
delivered in 5 seconds time (approximately the same time give or take a
few ms over the loop run.

In this case testStream is the actorRef. The behavior I have here is
unexpected. Instead of having each line messaged with a 5 second
delay, there is instead an initial delay of 5 seconds, then it seems
like testStream ! Message(line) is being invoked as it normally would
for the number of lines in the file. Instead what I was hoping was to
still retain that initial 5 second delay, send testStream a message,
go to the next line in the file, then send another Message in 5
seconds and so forth.
What am I doing wrong here that's causing that behavior to not go through?
Thanks for the help.
Matthew
