Metamodel Classes in the roster Application

Metamodel classes are classes that model an entities attributes, and are used by Criteria queries to navigate to an entities attributes. Each entity class in roster has a corresponding Metamodel class, generated at compile-time, with the same package name as the entity, and appended with an underscore character (_). For example, the roster.entity.Person entity has a corresponding Metamodel class, roster.entity.Person_.

Each persistent field or property in the entity class has a corresponding attribute in the entity's Metamodel class. For the Person entity, the corresponding Metamodel class is:

@StaticMetamodel(Person.class)
public class Person_ {
  public static volatile SingularAttribute<Player, String> id;
  public static volatile SingularAttribute<Player, String> name;
  public static volatile SingularAttribute<Player, String> position;
  public static volatile SingularAttribute<Player, Double> salary;
  public static volatile CollectionAttribute<Player, Team> teams;
}
