Examples of CollectionValuedPathExpression

org.eclipse.persistence.jpa.internal.jpql.parser.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.
BNF: collection_valued_path_expression ::= general_identification_variable.{single_valued_object_field.}*collection_valued_field
