title: In (android) Realm how do i sort a list based on a column by column multiplication?
body: <p>I got a realm object like so</p>
  
  <pre><code>public class MyItem extends RealmObject {
  public Product product;
  public double amount;
  }
  
  public class Product extends RealmObject {
  public double price;
  }
  </code></pre>
  
  <p>I would like to sort my realm list by MyItem(product.price*amount) ascending. How is this possible with Realm?</p>
