Colectica SDK: Find all referencing items, multiple levels away

GetReferencingItems.cs

Collection<IdentifierTriple> GetReferencingItems(RepositoryClientBase client, IdentifierTriple objectId, Guid subjectType)
{
	// The set search will look for items of the specified type
	// multiple levels away from the specified item.
	// Note that this will be slower than a graph search,
	// because the entire set must be determined.

	// The ReverseTraversal property indicates that we want to
	// find items that point *to* the specified item, instead
	// of items referenced *by* the specified item.
	SetSearchFacet facet = new SetSearchFacet()
	{
		ReverseTraversal = true
	};

	facet.ItemTypes.Add(subjectType);
	return client.SearchTypedSet(objectId, facet).ToIdentifierCollection();
