public sealed class HierarchyCollection : IDisposable, 
    IEnumerable, ICollection
public ref class HierarchyCollection sealed : IDisposable, 
    IEnumerable, ICollection
[<SealedAttribute>]
type HierarchyCollection =

The HierarchyCollection type exposes the following members.

Properties

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

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.
