IsDeferLoaded ( MemberInfo member ) : bool	Determines if a relationship property is included, but the query for the related data is deferred until the property is first accessed.
IsIncluded ( MemberInfo member ) : bool	Determines if a relationship property is to be included in the results of the query
QueryPolicy ( QueryMapping mapping ) : System
Translate ( Expression expression ) : Expression	Provides policy specific query translations. This is where choices about inclusion of related objects and how heirarchies are materialized affect the definition of the queries.
