    public class DataItemNavigationFilter

A step that filters a data item based on a specific kind of navigation on a particular member. There are a few types of navigation filters, each of which returns a different set of members. In order to navigate through the data, a hierarchy filter must be defined, or a hierarchy will need to be specified as part of this filter.
