code: public void update(Object object) {
          try {
              persistenceManager.saveEntity((IManagedEntity) object);
          } catch (InitializationException ignore){}
          catch (Exception e) {
              e.printStackTrace();
          }
      }
docs: Update an entity that must already exist.  Within onyx there is no differentiation
  between inserting and updating so either way it will call the saveEntity method
  
  @param object Object to update
