PersonAR is an Active Record which extends BaseAR. For a running example see the JavaActiveRecord-Example-Project or the unit tests of JavaActiveRecord.
// Saving an entity PersonAR person = new PersonAR(); person.setName("First name"); person.setSurname("Last name"); person.save(); System.out.println("Saved Person with ID: " + person.getId()); // Loading by ID PersonAR findById = PersonAR.findById(PersonAR.class, 1); System.out.println("Person by ID: " + findById); // Loading by custom field Collection<PersonAR> findByField = PersonAR.findAllByField(PersonAR.class, "name", "First name"); System.out.println("Person by Name: " + findByField); // Loading all Collection<PersonAR> findAll = PersonAR.findAll(PersonAR.class); System.out.println("All Persons: " + findAll);
