) : Task<IFilteredHierarchyItemSet>

Parameters

• sourceCollection
  Type: Microsoft.VisualStudio.Shell.IReadOnlyObservableSet<IVsHierarchyItem>

  The hierarchy items to filter.

• includeInFilter
  Type: System.Predicate<IVsHierarchyItem>

  The predicate used to determine what is included in the filtered set.

• cancellationToken
  Type: System.Threading.CancellationToken

  A cancellation token that can be used to cancel the asynchronous request.

• dependentProperties
  Type: array<System.Int32[]

  An optional set of property identifiers that indicate the hierarchy item properties that affect the filter and as a result cause the includeInFilter predicate to be re-queried.

Return Value

Type: System.Threading.Tasks.Task<IFilteredHierarchyItemSet>
A task that, when complete, provides the filtered set of hierarchy items.
