• Decided to get a copy (hopefully with student discount) of Atlas. It does taxonomic analysis and outputs a matrix to Excel that I should be able to use to produce PageRank???
• Timesheets! Done
• Seeing if I can add a bit of reflection to addXXX(YYY) that will invoke add/setYYY(XXX). Since the target is a map, it shouldn’t care, but I do need to worry about recursion…
• Added addSourceToTarget() and testSourceInTarget() to GuidBase. So Now addM2M looks like

  public void addM2M(GuidBase obj) throws Exception {
      System.out.println("person.addM2M");
      addSourceToTarget(this, obj);
      addSourceToTarget(obj, this);
  }

  and the example of Showroom.addCar() looks like

  public void addCar(Car car){
      if(cars == null){
          cars = new HashSet<>();
      }
      cars.add(car);
  
      try {
          if(!testSourceInTarget(this, car)){
              addSourceToTarget(this, car);
          }
      } catch (Exception e) {
          e.printStackTrace();
      }
  }

  Which now means that the two way mapping is automatic. And in case you’re wondering, testSourceInTarget looks first for a method that returns the source type, and then looks for a method that returns a Set<source type>. If it find the source in either one of those, it returns true.

• Got queries running. Simple queries are easy, but the more complex ones can be pretty ugly. Here’s an example that pulls a Showroom Object based on a nested Person Object (instanced as ‘customer’):

  // do a query based on a nested item's value. Kinda yucky...
  Criteria criteria = session.createCriteria(Showroom.class, "sh");
  criteria.createAlias("sh.customers", "c");
  List result = criteria.add(Restrictions.like("c.name", "%Aaron%")).list();
  for(Object o : result){
      System.out.println(o.toString());
  }
