With Android Room, do I need to add setter and getter for nested object?

Question

In the code below, class Address is nested in Entity User . I wonder if all the attributes of Address are private , do we need getter and setter for each of the field in Address ? Notice there is a List<String> , so I'm not sure if Room will work well with @TypeConverter in this case.

public class Address {
    public String street;
    public String state;
    public List<String> city;

    @ColumnInfo(name = "post_code")
    public int postCode;
}

@Entity
public class User {
    @PrimaryKey
    public int id;

    public String firstName;

    @Embedded
    public Address address;
}

Answer 1

You can easily add getter/setters with @Ignore annotation and the converter will ignore these methods.

 @Ignore 
 public List<String> getCity() {
     return city;
 }
