Table
,org.datanucleus.store.schema.table.Table
Representation of a join table for an array. An array requires ordering of elements so that they can be stored
and retrieved in the same order.
JoinTable Mappings
The join table consists of the following mappings :-
- ownerMapping linking back to the owning class with the Collection.
- elementMapping either being an FK link to the element table or being an embedded/serialised element stored wholely in this table.
- orderMapping providing the ordering of the elements.
