Learning Concurrency in Kotlin

CoroutineStart

By default, actors will be started as soon as they are created. You can pass a CoroutineStart to change this behavior according to what you need. For example:

val actor = actor<String>(start = CoroutineStart.LAZY) {    for (msg in channel) {        println(msg)    }}

In this case, the actor will be started when it first receives a message.

You can use all the other values of CoroutineStart as well, like DEFAULT, ATOMIC, and UNDISPATCHED.
