Sets the top level property filter. Currently, this object may be either a clause or a statement. A clause is simply a container item which in turn contains some number of additional clauses or statements. The clause object is accessed through the IPTPropertyFilterClauses interface and the statement object is accessed through the IPTPropertyFilterStatement interface, both of which extend the IPTPropertyFilterItem interface from which a GetType method is provided for convenience.
