Object Types & Schemas

Realm applications model data as objects composed of property-value pairsthat each contain one or more primitive data types or other Realmobjects. Realm objects are essentially the sameas regular objects, but they inherit fromRealmObject orEmbeddedObject and includeadditional features likereal-time updating data views and reactivechange event handlers.

Every Realm object has anobject type that refers to the object'sclass. Objects of the same type share anobject schema that defines the properties and relationships of thoseobjects.

Working with Realm Objects

The following code block shows an object schema that describes a Dog.Every Dog object must include aName and mayoptionally include the dog'sAge,Breed and a list of people thatrepresents the dog'sOwners.

publicpartialclassDog :IRealmObject
{
    [PrimaryKey]
    [MapTo("_id")]
public ObjectId Id {get;set; }
publicstring Name {get;set; }
publicint Age {get;set; }
publicstring Breed {get;set; }
public IList<Person> Owners {get; }
}
publicpartialclassPerson :IRealmObject
{
    [PrimaryKey]
    [MapTo("_id")]
public ObjectId Id {get;set; }
publicstring Name {get;set; }
// etc...
/* To add items tothe IList<T>:
    var dog = new Dog();
    var caleb = new Person { Name = "Caleb" };
    dog.Owners.Add(caleb);
    */
}
