public final class CollectionValuedPathExpression extends AbstractPathExpression
Acollection_valued_fieldis 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 acollection_valued_fieldis 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- Version:
