Parse Object: How to identify properties that have changed?

Hi everyone,

I would like to know if there is an existing method/recommended approach, for Parse.Object, to identify the properties that have changed, in a BeforeSave Trigger?

My use-case:
When a BeforeSave Trigger is executed, i would like to be able to easily detect which all properties have changed b/w request.object and request.original. So that, i can then perform necessary actions (in a particular order) only on the fields for which the data has changed.

Kindly advise.

In the beforeSave trigger request you will find two parameters, original and object. You can compare the properties of these two parameters and find out which attributes have changed.
