public final class CollectionValuedPathExpression
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.
