java.lang.Object
org.datanucleus.store.rdbms.scostore.IteratorStatement
Direct Known Subclasses:
ElementIteratorStatement, KeyValueIteratorStatement
public abstract class IteratorStatement extends Object
Representation of the SQLStatement for an iterator of a container (map, collection, or array). An iterator statement can be an iterator for a single owner, or a bulk iterator for multiple owners (in which case the ownerMapIndex will be set so we can check the owner for the element/key/value. This will be extended for a collection/array element or map key/value dependent on which type we represent.
