Provides methods and events that are required for LiveLinq functionality, indexing and live views.

Object Model

Syntax

Visual Basic
C#

'Declaration
 
Public Interface IObservableSource(Of T)

public interface IObservableSource<T>

Type Parameters

T: The type of the elements in the collection.

Remarks

Indexing and live view functionality is available for any collection that supports change notifications necessary for maintaining indexes and live views, that is, fires events when an item is added to or removed from the collection and when a property of the item changes. So, the members of this interface are mostly concerned with providing such notifications.

Classes implementing this interface usually also implement C1.LiveLinq.Indexing.IIndexedSource<T>.

Both these interfaces are implemented by all main LiveLinq collection classes: C1.LiveLinq.Collections.IndexedCollection<T>, C1.LiveLinq.AdoNet.IndexedDataTable<TRow>, C1.LiveLinq.LiveViews.View<T>.

You need to implement this interface only if you want to define your own indexable collection classes and then only if they don't inherit from C1.LiveLinq.Collections.IndexedCollection<T>, see LiveLinq to Objects: IndexedCollection(T) and other collection classes.

Requirements

Target Platforms: Windows 7, Windows Vista SP1 or later, Windows XP SP3, Windows Server 2008 (Server Core not supported), Windows Server 2008 R2 (Server Core supported with SP1 or later), Windows Server 2003 SP2
