A readonly observable collection that provides for constant time Contains look up.

generic <typename T>
public interface class IReadOnlyObservableSet : Microsoft::VisualStudio::Shell::IReadOnlyObservableSet, System::Collections::Generic::IEnumerable<T>, System::Collections::Specialized::INotifyCollectionChanged

public interface IReadOnlyObservableSet<T> : Microsoft.VisualStudio.Shell.IReadOnlyObservableSet, System.Collections.Generic.IEnumerable<T>, System.Collections.Specialized.INotifyCollectionChanged

type IReadOnlyObservableSet<'T> = interface
    interface IReadOnlyObservableSet
    interface IEnumerable
    interface INotifyCollectionChanged
    interface seq<'T>

Public Interface IReadOnlyObservableSet(Of T)
Implements IEnumerable(Of T), INotifyCollectionChanged, IReadOnlyObservableSet

Type Parameters

T

The type of items stored in the set.

Derived: Microsoft.VisualStudio.Shell.IFilteredHierarchyItemSet

Microsoft.VisualStudio.Shell.ReadOnlyObservableSet<T>

Implements: IReadOnlyObservableSet IEnumerable<T> IEnumerable INotifyCollectionChanged

Remarks

This interface is used by the ReadOnlyObservableSet<T> base class to specifically filter hierarchy items (not progressive nodes) in a solution filter. If you are creating a solution filter from scratch, use IReadOnlyObservableSet.

Properties

Name	Description
Count	Gets the number of elements contained in the IReadOnlyObservableSet. (Inherited from IReadOnlyObservableSet)

Methods

Name	Description
Contains(Object)	Determines whether the IReadOnlyObservableSet contains a specific value. (Inherited from IReadOnlyObservableSet)
Contains(T)	Determines whether the IReadOnlyObservableSet<T> contains a specific value.

Extension Methods

Name	Description
EmptyIfNull<T>(IEnumerable<T>)	Return this enumeration in case it is not null. In case it is null return empty enumeration.
