Properties

BacklinksCount

Gets the number of objects referring to this one via either a to-one or to-many relationship.

Declaration

public int BacklinksCount { get; }

Property Value

Type	Description
Int32

Remarks

This property is not observable so the PropertyChanged event will not fire when its value changes.

IsManaged

Gets a value indicating whether the object has been associated with a Realm, either at creation or via Add(RealmObject, Boolean).

Declaration

public bool IsManaged { get; }

Property Value

Type	Description
Boolean	`true` if object belongs to a Realm; `false` if standalone.

| Improve this Doc View Source

IsValid

Gets a value indicating whether this object is managed and represents a row in the database. If a managed object has been removed from the Realm, it is no longer valid and accessing properties on it will throw an exception. Unmanaged objects are always considered valid.

Declaration

public bool IsValid { get; }

Property Value

Type	Description
Boolean	`true` if managed and part of the Realm or unmanaged; `false` if managed but deleted.

ObjectSchema

Gets the ObjectSchema instance that describes how the Realm this object belongs to sees it.

Declaration

Property Value

Type	Description
ObjectSchema	A collection of properties describing the underlying schema of this object.

Implements

ISchemaSource.ObjectSchema

Finalize()

OnManaged()

Called when the object has been managed by a Realm.

Declaration

protected virtual void OnManaged()

Remarks

This method will be called either when a managed object is materialized or when an unmanaged object has been added to the Realm. It can be useful for providing some initialization logic as when the constructor is invoked, it is not yet clear whether the object is managed or not.

OnPropertyChanged(String)

Called when a property has changed on this class.

Declaration

protected virtual void OnPropertyChanged(string propertyName)

Parameters

Type	Name	Description
String	propertyName	The name of the property.

Remarks

For this method to be called, you need to have first subscribed to PropertyChanged. This can be used to react to changes to the current object, e.g. raising PropertyChanged for computed properties.

Examples

class MyClass : RealmObject
{
    public int StatusCodeRaw { get; set; }
    public StatusCodeEnum StatusCode => (StatusCodeEnum)StatusCodeRaw;
    protected override void OnPropertyChanged(string propertyName)
    {
        if (propertyName == nameof(StatusCodeRaw))
        {
            RaisePropertyChanged(nameof(StatusCode));
        }
    }
}

Here, we have a computed property that depends on a persisted one. In order to notify any PropertyChanged subscribers that StatusCode has changed, we override OnPropertyChanged(String) and raise PropertyChanged manually by calling RaisePropertyChanged(String).

RaisePropertyChanged(String)

Allows you to raise the PropertyChanged event.

Declaration

protected void RaisePropertyChanged(string propertyName = null)

Parameters

Type	Name	Description
String	propertyName	The name of the property that has changed. If not specified, we'll use the caller name.

Events
