[hibernate-issues] [Hibernate-JIRA] Commented: (HHH-4417) Add annotation support for UserCollectionType
[
https://hibernate.onjira.com/browse/HHH-4417?page=com.atlassian.jira.plug...
]
Steve Ebersole commented on HHH-4417:
-------------------------------------
The only sticking point with auto determination (and IIUC this exists today in the
annotation code anyway) is if you have something like:
{code:borderStyle=solid}
public class UniqueList implements java.util.Set, java.util.List {
...
}
{code}
If we need explicit specification of collection type (in the "Java
type"/{{javax.persistence.metamodel.PluralAttribute.CollectionType}} sense) then I
think:
* that should be a separate issue (again it exists in the old existing code before these
changes as well)
* the solution should leverage org.hibernate.metamodel.domain.PluralAttributeNature, maybe
exposed as an attribute on the {{org.hibernate.annotations.CollectionType}} annotation
introduced by this issue, although TBH I think a separate annotation makes more sense.
Add annotation support for UserCollectionType

Key: HHH-4417
URL: https://hibernate.onjira.com/browse/HHH-4417
Project: Hibernate ORM
Issue Type: Patch
Components: annotations
Environment: All versions, database agnostic
Reporter: Douglas Sjoquist
Assignee: Steve Ebersole
Priority: Minor
Fix For: 4.1.1
Attachments: UserCollectionTypeAnnotation.zip
Original Estimate: 0.5h
Time Spent: 0.45h
Remaining Estimate: 0.5h
Add an annotation to specify the UserCollectionType for a OneToMany or ManyToMany.
The annotation is named CollectionTypeInfo, perhaps better named UserCollectionType, but
I didn't know the standards for naming classes.
The change to AnnotationBinder is minor and is delineated by '//dwsjoquist//'
comment lines.
Usage:
@OneToMany(fetch = FetchType.LAZY, cascade = CascadeType.ALL)
@JoinColumn(name = "id")
@CollectionTypeInfo(name = "examples.MyUserCollectionType")
public List<ExampleAttribute> getExampleAttributes() {
