Enroscar Async
Makes it easy to put your asynchronous operations behind Android's Loader.
Main abstraction here is Async which represents some asynchronous operation.
How it is used
Read our recipes page. Here is a quick overview.
Describe an asynchronous operation.
class Foo {
@Load Async<String> loadGreeting(final String name) {
return Tools.async(new Callable<String>() {
public String call() {
try {
Thread.sleep(1000);
}
catch (InterruptedException ignored) {
}
return "Hello " + name;
}
}
);
}
}
In this example we create a simple Callable and pass it to Tools.async method that constructs an Async implementation running our Callable in Android's AsyncTask.
An annotations processor generates an operator class FooOperator that can be used to start/cancel your operations or subscribe to their execution results. Use it!
// this an object that provides operations Foo foo = new Foo();
// prepare the operator // FooOperator is a generated class FooOperator operator = FooOperator.build()
.withinActivity(activity)
.operations(foo)
.get();
// subscribing operator.when().loadGreetingIsFinished()
.doOnResult(new Action<String>() {
@Override
public void act(final String greeting) {
Log.i("Async", "Greeting loaded: " + greeting);
}
}
);
// starting operator.loadGreeting();
// cancelling operator.cancelLoadGreeting();
Note that working with an operator you actually control an Android Loader. Hence, using it within an Activity or Fragment you do not care about their lifecycle. Actions you provide subscribing to operations will be automatically attached to running tasks during Activity recreation.
