Can you explain Inverse="true" ?.

http://simoes.org/docs/hibernate-2.1/155.html

I just want to know at what situation inverse="true" should be used and what is the difference between cascade and inverse?.

Thanks

Hi,

The both attributes may use in <set> element.

Cascade attribute is used to cascade the child entity, while saving/updating/deleting the parent entity.

Inverse attribute is used to mention either parent or child entity can take care of the relationship for these entities.

for example,

<set inverse="true"
name="par"> - parent entity will take care of relationship handling for child.

<set inverse="false"
name="par"> - child entity will take care of relationship handling for child.

i.e

insert into parent(id,name) values(?,?)
insert into child(id,name,parent_id) values(?,?,null)
update child set parent_id=? where id=?

Thanks.
