<div class="block">A <code>GetCallback</code> is used to run code after a <a href="../../com/parse/ParseQuery.html" title="class in com.parse"><code>ParseQuery</code></a> is used to fetch a
 <a href="../../com/parse/ParseObject.html" title="class in com.parse"><code>ParseObject</code></a> in a background thread.
 <p/>
 The easiest way to use a <code>GetCallback</code> is through an anonymous inner class. Override the
 <code>done</code> function to specify what the callback should do after the fetch is complete.
 The <code>done</code> function will be run in the UI thread, while the fetch happens in a
 background thread. This ensures that the UI does not freeze while the fetch happens.
 <p/>
 For example, this sample code fetches an object of class <code>"MyClass"</code> and id
 <code>myId</code>. It calls a different function depending on whether the fetch succeeded or not.
 <p/>
 <pre>
 ParseQuery&lt;ParseObject&gt; query = ParseQuery.getQuery(&quot;MyClass&quot;);
 query.getInBackground(myId, new GetCallback&lt;ParseObject&gt;() {
   public void done(ParseObject object, ParseException e) {
