embedded

public boolean embedded

Define objects of this type as "Embedded". Embedded objects have a slightly different behavior than normal objects:

  • They must have exactly 1 parent linking to them when the embedded object is added to the Realm. Embedded objects can be the parent of other embedded objects. The parent cannot be changed later, except by copying the object.

  • They cannot have fields annotated with @PrimaryKey .

  • When a parent object is deleted, all embedded objects are also deleted.

  • It is possible to define an easy reference to the parent object using the @LinkingObjects annotation:

    @LinkingObjects
    public Parent parent;

Default: false

fieldNamingPolicy

public RealmNamingPolicy fieldNamingPolicy

The naming policy applied to all fields in this class. The default policy is RealmNamingPolicy.NO_POLICY .

It is possible to override the naming policy for each field by using the RealmField annotation.

Default: io.realm.annotations.RealmNamingPolicy.NO_POLICY
