Direct Known Subclasses:

ElementIteratorStatement, KeyValueIteratorStatement

public abstract class IteratorStatement
extends java.lang.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.
