Class RefreshCallback<T extends AVObject>

java.lang.Object

com.avos.avoscloud.AVCallback<T>

com.avos.avoscloud.RefreshCallback<T>

public abstract class RefreshCallback<T extends AVObject>
extends AVCallback<T>

A RefreshCallback is used to run code after refresh is used to update a AVObject in a background thread.

The easiest way to use a RefreshCallback is through an anonymous inner class. Override the done function to specify what the callback should do after the refresh is complete. The done function will be run in the UI thread, while the refresh happens in a background thread. This ensures that the UI does not freeze while the refresh happens.

For example, this sample code refreshes an object of class "MyClass" and id myId. It calls a different function depending on whether the refresh succeeded or not.

 object.refreshInBackground(new RefreshCallback() {
   public void done(AVObject object, AVException e) {
     if (e == null) {
       objectWasRefreshedSuccessfully(object);
     } else {
       objectRefreshFailed();
     }
   }
 });
