[rules-users] Can someone help me understand a java rule? [planner]

[Aijin Nakanishi]

I mean, i know how it is called, it is inside the xml configuration:
----------
  <!-- Domain model configuration -->

<solutionClass>org.drools.planner.examples.cloudbalancing.domain.CloudBalance</solutionClass>

<planningEntityClass>org.drools.planner.examples.cloudbalancing.domain.CloudProcess</planningEntityClass>

  <!-- Score configuration -->
  <scoreDirectorFactory>
    <scoreDefinitionType>HARD_AND_SOFT</scoreDefinitionType>

<simpleScoreCalculatorClass>org.drools.planner.examples.cloudbalancing.solver.score.CloudBalancingSimpleScoreCalculator</simpleScoreCalculatorClass>-->

  </scoreDirectorFactory>
---------

i want to understant the java class doing the assign to cloudcomputers. I
don't see any setCloudProcess to a CloudComputer, even so, when the planner
ends, all process have been distributed to cloudcomputer. That's what I am
trying to understand, how does it works. I did a debug but i didn't catch
the moment a cloud computer receives a cloudprocess
