Debounce and Throttle dispatchers support asynchronous actions, handle exceptions. All Task results from dispatcher calls will be equal to result of the a single invoking.
Show entered text after stopping pressing keys for 1000 milliseconds
class Program
{
static void Main(string[] args)
{
string str = "";
var debounceDispatcher = new DebounceDispatcher(1000);
while(true)
{
var key = Console.ReadKey(true);
//trigger when to stop and exit
if (key.Key == ConsoleKey.Escape) break;
str += key.KeyChar;
//every keypress iteration call dispatcher but the Action will be invoked only after stopping pressing and waiting 1000 milliseconds
debounceDispatcher.Debounce(() =>
{
Console.WriteLine($"{str} - {DateTime.UtcNow.ToString("hh:mm:ss.fff")}");
str = "";
});
}
}
}Call action every 100 milliseconds but invoke only once in 1000 milliseconds (after last invoking completed)
class Program
{
static void Main(string[] args)
{
bool stop = false;
//trigger when to stop and exit
Task.Run(() => { Console.ReadKey(true); stop = true; });
var throttleDispatcher = new ThrottleDispatcher(1000);
do
{
//every iteration call dispatcher but the Action will be invoked only once in 1500 milliseconds (500 action work time + 1000 interval)
throttleDispatcher.ThrottleAsync(async () =>
{
Console.WriteLine($"{ DateTime.UtcNow.ToString("hh:mm:ss.fff") }");
await Task.Delay(500);
});
//iteration every 100 milliseconds
Thread.Sleep(100);
}
while (!stop); //wait trigger to stop and exit
}
