title: How to represent nested @Relation with Android Room?
body: <p>Here is my POJO in kotlin:</p>
  
  <pre><code>data class Pass(var uuid: String,
                  var activationRestrictions:List&lt;ActivationRestriction&gt;)
  
  
  data class ActivationRestriction(var uuid: String,
                                   var activationRestrictionExceptions:List&lt;ActivationRestrictionException&gt;)
  
  
  data class ActivationRestrictionException(var uuid: String)
  </code></pre>
  
  <p>How can I represent this nested relation with Room? <a href="https://stackoverflow.com/questions/44330452/android-persistence-room-cannot-figure-out-how-to-read-this-field-from-a-curso/44424148#44424148">Here</a> is one of the solution, but it does not contain a nested relation. I am specifically looking for solving a nested relationship with Room.</p>
