Inheritance Hierarchy

System.Object
Microsoft.AnalysisServices.AdomdServer.HierarchyCollection

Namespace: Microsoft.AnalysisServices.AdomdServer
Assembly: msmgdsrv (in msmgdsrv.dll)

Syntax

'Declaration
Public NotInheritable Class HierarchyCollection _
    Implements IDisposable, IEnumerable, ICollection
'Usage
Dim instance As HierarchyCollection

public sealed class HierarchyCollection : IDisposable, 
    IEnumerable, ICollection

public ref class HierarchyCollection sealed : IDisposable, 
    IEnumerable, ICollection

[<SealedAttribute>]
type HierarchyCollection =  
    class
        interface IDisposable
        interface IEnumerable
        interface ICollection
    end

public final class HierarchyCollection implements IDisposable, IEnumerable, ICollection

The HierarchyCollection type exposes the following members.

Properties

	Name	Description
	Count	Gets the number of Hierarchy objects in the collection.
	IsSynchronized	Gets a value indicating whether access to the collection is synchronized (thread safe).
	Item[Int32]	Gets the specified Hierarchy from the collection by its index. In Microsoft Visual C#, this property is the indexer for the HierarchyCollectionclass.
	Item[String]	Gets the specified Hierarchy from the collection by its name. In Microsoft Visual C#, this property is the indexer for the HierarchyCollectionclass.
	SyncRoot	Gets an object that can be used to synchronize access to the collection.

	CopyTo(Array, Int32)	Copies the elements of the collection to the specified array.
	CopyTo(array<Hierarchy[], Int32)	Copies the elements of the collection to the specified array.
	Dispose	Releases all resources used by the HierarchyCollection.
	Equals	(Inherited from Object.)
	Finalize	(Inherited from Object.)
	Find	Gets the specified Hierarchy from the collection by its name.
	GetEnumerator()	Gets an Enumerator for iterating through the collection.
	GetEnumerator()
	GetHashCode	(Inherited from Object.)
	GetType	(Inherited from Object.)
	MemberwiseClone	(Inherited from Object.)
	ToString	(Inherited from Object.)

Remarks

While the HierarchyCollection externally represents a collection of Hierarchy objects, the collection is internally loaded and managed in one of two ways, depending on the parent of the collection:

If the parent object was referenced as a result of a query, as in the case of a Set referenced from a Axis, the collection represents the members referenced by that query.
If the parent object was referenced as a result of a request for metadata, as in the case of a Dimension referenced from a CubeDef, the collection represents the members referenced by the definition of the parent object.

Thread Safety

Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
