Class DeleteCallback

java.lang.Object

com.avos.avoscloud.AVCallback<Void>

com.avos.avoscloud.DeleteCallback

public abstract class DeleteCallback
extends AVCallback<Void>

A DeleteCallback is used to run code after saving a AVObject in a background thread.

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

For example, this sample code deletes the object myObject and calls a different function depending on whether the save succeeded or not.

 myObject.deleteInBackground(new DeleteCallback() {
   public void done(AVException e) {
     if (e == null) {
       myObjectWasDeletedSuccessfully();
     } else {
       myObjectDeleteDidNotSucceed();
     }
   }
 });
