Annotation Interface Bag

@Target({METHOD,FIELD,ANNOTATION_TYPE})
@Retention(RUNTIME)
public @interface Bag

Specifies that an attribute of type List is semantically a bag - that the order of the list elements is not significant, and should not be persistent.

This annotation is not necessary, and has no effect, unless the configuration property "hibernate.mapping.default_list_semantics" is set to CollectionClassification.LIST. However, its use is still encouraged, since the explicit annotation serves as useful documentation.

API Note:

This annotation causes an exception if the attribute is also annotated OrderColumn or ListIndexBase.
