如何在我的自定义对象中正确实现领域列表？

Question

So I'm trying to implement a Realm List into my class, however, the documentation that I can find at Realm.io doesn't clarify whether it needs a getter/setter and if it does what it should look like. So here's my code:

public class Novel extends RealmObject {

   @PrimaryKey
   private static int id;

   @Required
   private static String name;

   //Establish relationship with Novel (single) and Chapter (many)
   private RealmList<Chapter> chapters;

   public static int getId() {
       return id;
   }//end getId

   public static void setId(int id) {
       Novel.id = id;
   }//end setId

   public static String getName() {
    return name;
   }//end getName

   public static void setName(String name) {
    Novel.name = name;
   }//end setName

}//end Novel.class

In order to store an object in a Realm Database, all variables have to have getters/setters. However, since I am using a RealmList , how do I structure my getter/setter correctly?

Here's the code Android Studio gives me, but it just doesn't look right.

public RealmList<Chapter> getChapters() {
    return chapters;
}

public void setChapters(RealmList<Chapter> chapters) {
    this.chapters = chapters;
}

The getter looks ok, however, the setter makes no sense to me in how it would work with the RealmList correctly.

tldr : What should my getter/setter be in order to properly implement the RealmList in my custom object?

Answer 1

RealmList implements all useful interfaces:

java.lang.Iterable<E>, java.util.Collection<E>, java.util.List<E>

If you want to add new Chapter to the Novel use code similar to:

Chapter chapter = realm.copyToRealm(new Chapter());
novel.getChapters().add(chapter);

If you want to replace all chapters with new one:

RealmList<Chapter> chapters = new RealmList<Chapter>();
chapters.add(new Chapter());
chapters.add(new Chapter());
chapters.add(new Chapter());
chapters.add(new Chapter());

chapters = realm.copyToRealm(chapters);
novel.setChapters(chapters);
