HierarchyTreeFilterProvider.HierarchyTreeFilter Class

Base class that implements some of the boilerplate parts of an ISolutionTreeFilter. This includes behavior to ensure newly-added hierarchy items are always visible through the filtered view, even if those items do not match the filter. Derived types must still implement the logic for constructing the set of included items.

Public method Equals Determines whether the specified object is equal to the current object. (Inherited from Object.)
Protected method Finalize Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from DisposableObject.)
Public method GetFilterDescendantsBehavior Indicates whether to include descendants if none are explicitly specified.
Public method GetHashCode Serves as a hash function for a particular type. (Inherited from Object.)
Protected method GetIncludedItemsAsync
Public method GetType Gets the Type of the current instance. (Inherited from Object.)
Protected method MemberwiseClone Creates a shallow copy of the current Object. (Inherited from Object.)
Protected method ThrowIfDisposed Throws an ObjectDisposedException if this object has been disposed. (Inherited from DisposableObject.)
Public method ToString Returns a string that represents the current object. (Inherited from Object.)
