title: Is it possible to have a computed property on Google App Engine using Java?
body: <p>I have an app engine application and I want to run a query that sorts the result based on a expression involving two properties. Best way I thought of doing it so far is to create a computed/calculated property that stores the result of that expression. Although I saw that GAE in Python offers a ComputedProperty, which seems to be exactly what I'm looking for, I couldn't find an equivalent in Java.</p>
  
  <p>I'm currently using Objectify too, if that helps.</p>
  
  <p>Any ideas?</p>
