Interface FunctionCallback<T>

  • Type Parameters:
    T - The type of object returned by the Cloud Function.

    public interface FunctionCallback<T>
    A FunctionCallback is used to run code after ParseCloud.callFunction(java.lang.String, java.util.Map<java.lang.String, ?>) is used to run a Cloud Function in a background thread.

    The easiest way to use a FunctionCallback is through an anonymous inner class. Override the done function to specify what the callback should do after the cloud function is complete. The done 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.

    For example, this sample code calls a cloud function "MyFunction" with params and calls a different function depending on whether the function succeeded.

     ParseCloud.callFunctionInBackground("MyFunction"new, params, FunctionCallback() {
       public void done(ParseObject object, ParseException e) {
         if (e == null) {
         } else {

        Override this function with the code you want to run after the cloud function is complete.
        object - The object that was returned by the cloud function.
        e - The exception raised by the cloud call, or null if it succeeded.
