@Documented
@Retention(value=RUNTIME)
@Target(value={FIELD,TYPE})
public @interface Since
This annotation has no effect unless you build Gson with a
GsonBuilder and invoke
GsonBuilder.setVersion(double) method.
Here is an example of how this annotation is meant to be used:
public class User {
private String firstName;
private String lastName;
@Since(1.0) private String emailAddress;
@Since(1.0) private String password;
@Since(1.1) private Address address;
}
If you created Gson with new Gson(), the toJson() and fromJson()
methods will use all the fields for serialization and deserialization. However, if you created
Gson with Gson gson = new GsonBuilder().setVersion(1.0).create() then the
toJson() and fromJson() methods of Gson will exclude the address field
since it's version number is set to 1.1.
