| com.triactive.jdo.store.SetStore
All known Subclasses: com.triactive.jdo.store.AbstractSetStore,
| SetStore | | public interface SetStore (Code) | | Implements the backing store for a Set field.
Different implementations of SetStore employ different techniques for
modeling the Java concept of a Set in a relational data store.
Individual instances of SetStore are responsible for managing the storage
for some Java class's Collection or Set field across all instances of that
class.

| getExistsSubquery | | QueryStatement getExistsSubquery(QueryStatement.QueryColumn ownerIDColumn, SQLIdentifier setRangeVar)(Code) | | Create a subquery for the given query that joins a SetStores
element table to the owner table. This subquery can subsequently be used
in an EXISTS expression to determine whether a Set is empty or not.
Parameters:
ownerIDColumn - The QueryColumn of the owner ID.
Parameters:
setRangeVar - The range variable for the "Set" table. A subquery for the given query that joins a SetStoreselement table to the owner table. |
