Class FunctionCallback<T>
Object
com.parse.FunctionCallback<T>
- Type Parameters:
E
- The type of object returned by the Cloud Function.
public abstract class FunctionCallback<T>
- extends Object
A FunctionCallback is used to run code after ParseCloud.callFunction(java.lang.String, java.util.Map)
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) {
cloudFunctionSucceeded(object);
} else {
cloudFunctionFailed();
}
}
});
