Raghu Nair: Java,JavaFX Tips

Async Task APIs are located in javafx.async package.  These APIs provides a way of starting, stopping and tracking code that does not run on the JavaFX event dispatch thread.

Now let us see  how we can use this API.

 Step1:  implement  RunnableFuture Interface and create you Task.

For example -

public class MyTask implements RunnableFuture {

public void run() throws Exception {
   //Place your code which you want to execute.
   println("Executing the task...");   
}

}

Note: Only Java Tasks can be specified here. 

Step2: Create JavaTaskBase in your FX code and in create() method return a instance of MyTask.

var task = JavaTaskBase {

public override function create(): RunnableFuture{
        return new MyTask() as RunnableFuture;
}
onDone: function():Void {  println("I am done..");}
onStart : function():Void {  println("About to start");

}

 task.start();
