Grails / GORM - equivalent to JPA @ElementCollection -

i have composition pattern parent object has list of child objects, e.g., order , lineitem.

it behaves similar cascading delete orphans, child objects @embeddables instead of @entities, , don't own ids - they're managed through parent object.

in jpa ensure whenever save order, collection of lineitems synchronize, including deleting removed items:

public class order {   @elementcollection   @collectiontable(...)    private set<lineitem> items;  } 

in grails, what's equivalent?

i can hasmany cascade all-delete-orphan prefer if there similar way child objects not have own ids (basically, not entities).

you can use static embedded in order. refer this.
