IndexedCollection<T> Class

Data collection class recommended for use in LiveLinq to Objects.

Object Model

Syntax

Visual Basic
C#

'Declaration
 
Public Class IndexedCollection(Of T) 
   Inherits System.Collections.ObjectModel.Collection(Of T)
   Implements C1.LiveLinq.Indexing.IIndexedSource(Of T), C1.LiveLinq.IObservableSource(Of T)

public class IndexedCollection<T> : System.Collections.ObjectModel.Collection<T>, C1.LiveLinq.Indexing.IIndexedSource<T>, C1.LiveLinq.IObservableSource<T>

Type Parameters

T: The type of the elements in the collection.

Remarks

If you don't have preexisting collection classes and need to create your own, the best choice is to use the built-in LiveLinq collection class IndexedCollection<T>. It is specifically optimized for LiveLinq use.

Usually, the element class T must implement the property change notification interface System.ComponentModel.INotifyPropertyChanged. The easiest way to implement System.ComponentModel.INotifyPropertyChanged is to derive the element class from IndexableObject.

In rare cases where implementing System.ComponentModel.INotifyPropertyChanged is impossible, a custom C1.LiveLinq.Listeners.PropertyChangeListener<T> can be provided instead.

For details, see Using the built-in collection class IndexedCollection(T) (LiveLinq to Objects).

For alternative options in LiveLinq to Objects, see LiveLinq to Objects: IndexedCollection(T) and other collection classes

The IndexedCollection<T> class is not needed in LiveLinq to DataSet and LiveLinq to XML, because in those cases LiveLinq works with collections that already exist in ADO.NET and XML.
