public class CollectionValuedPathExpressionStateObject
A collection-valued field is designated by the name of an association field in a one-to-many or a many-to-many relationship or by the name of an element collection field. The type of a collection-valued field is a collection of values of the abstract schema type of the related entity or element type.
