Detailed Description

Query Node objects are non-persistent helper objects used to form From Expressions, Selections, Orderings, and Query Expression. They are basically just a collection of properties. Object valued properties of Query Node objects are maintained by reference. This means that an internal interface pointer is kept internally in Query Node objects. Query Node objects form a hierarchy rooted at the Query object. The hierarchy can be traversed from the root downward by getting the value of object valued properties.
