Learning Concurrency in Kotlin

LinkedListChannel

If you want a channel in which you are able to send an unlimited amount of elements without it suspending, then you need a LinkedListChannel. This type of channel will not suspend any senders. In order to instantiate this type of channel, you can use the constructor:

val channel = LinkedListChannel<Int>()

You can also use the Channel() function with the parameter Channel.UNLIMITED:

val channel = Channel<Int>(Channel.UNLIMITED)

Channel.UNLIMITED is equal to Int.MAX_VALUE, so sending either of them to Channel() will retrieve an instance of LinkedListChannel.

This channel will never suspend a sender. So for example consider the following code:

fun main(args: Array<String>) = runBlocking {    val time = measureTimeMillis {        val ...
