Annotation Type Frozen

@Retention(value=RUNTIME)
 @Target(value={FIELD,TYPE_USE})
 @Documented
public @interface Frozen

Annotation to indicate that a type is frozen. Examples:

 @UDT
 public class Address{
 @Column
 private String street;

 @Column
 private int number;

 @Column
 private int zipCode;

 ...
 }

 @Table
 public class UserEntity {

 ...

 @Column
 @Frozen
 private Address address;
 }

 

It can be used in nested data types too:

 @Column
 private List<@Frozen Address> addresses;
 

Nested collections inside collections should be frozen too;

 @Column
 private Map<Integer,@Frozen List<String>> nestedCollections;
