|
| - * A simple tool to make waiting for the result of an asynchronous operation easy.
|
| - *
|
| - * This class is thread-safe; the result can be provided and retrieved on any thread.
|
| - *
|
| - * Example usage:
|
| - *
|
| - * final SimpleFuture<Integer> future = new SimpleFuture<Integer>();
|
| - * getValueAsynchronously(new Callback<Integer>() {
|
| - * public void onResult(Integer result) {
|
| - * // Do some other work...
|
| - * future.provide(result);
|
| - * }
|
| - * }
|
| - * int value = future.get();
|
| - *
|
| - * Or, if your callback doesn't need to do anything but provide the value:
|
| - *
|
| - * SimpleFuture<Integer> result = new SimpleFuture<Integer>();
|
| - * getValueAsynchronously(result.createCallback());
|
| - * int value = result.get();
|
| - *
|
| - * @param <V> The type of the value this future will return.
