public interface AsyncProvider<T,F>

An object capable of providing an instance of type T asynchronously via Callback. For example, the instance might be created within a GWT.runAsync block using the following template:

      public void get(final Callback callback) {
        GWT.runAsync(new RunAsyncCallback() {
          public void onSuccess() {
            callback.onSuccess(javax.inject.Provider.get());
          }
          public void onFailure(Throwable ex) {
            callback.onFailure(ex);
          }
        }
      }
