Class Summary

AbstractAcceptingRowIterator	Abstract base DelegatingRowIteratorthat excludes Rows that are not acceptable.
AbstractFilteringRowIterator
AbstractJoinedRowIterator
BaseRowIterator	An abstract base implementation of RowIterator.
ChainedRowIterator	Chains together one or more RowIterators to make them look like one (similiar to a SQL UNION).
ChangingIndexedRowIterator	A DelegatingRowIteratorthat is wraps a RowIteratorfrom some Index, and that can be resetto recreate the iterator for a new bound value.
CollatingRowIterator	Collates the results of two or more sorted RowIterators according to the given RowComparator.
DelegatingRowIterator	An abstract base RowIteratorthat delegates all calls to a wrapped instance.
DistinctRowIterator	A DelegatingRowIteratorimplementing DISTINCT.
EmptyRowIterator	A RowIteratorthat contains no Rows.
FilteringChangingIndexedRowIterator
FilteringRowIterator	A DelegatingRowIterator that only returns Rows that match a given WhereNode.
GroupedRowIterator	Processes a "raw" iterator to implement GROUP BY functionality.
IndexNestedLoopJoinedRowIterator	The Index Nested Loop Join or Augmented Nested Loop Join (ANL) is by far the most common join method and is the classic Axion join method.
JoinRowIterator	A RowIterator that simply wraps a ListIterator.
LazyRowRowIterator	A RowIteratorthat creates LazyRows based upon a list of Rowidentifiers.
LimitingRowIterator	RowIteratorimplementing LIMIT and OFFSET.
ListIteratorRowIterator	A RowIteratorthat simply wraps a ListIterator.
ListRowIterator	A RowIteratorthat for a given List.
NestedLoopJoinedRowIterator	A Nested Loop Join is performed by doing a scan over the left subtree and for each row in it performing a full scan of the right subtree.
RebindableIndexedRowIterator	A DelegatingRowIterator that is wraps a RowIterator from some Index, and that can be reset to recreate the iterator for a new bound value.
ReverseSortedRowIterator	Reverse a SortedRowIterator.
RowIteratorRowDecoratorIterator	A RowDecoratorIteratorbased upon some decoratorand RowIterator.
RowViewRowIterator	A RowIteratorthat creates RowViews based upon selected Rowidentifiers.
SingleRowIterator	A RowIteratorover a single Row.
SortedRowIterator
SortedRowIterator.MergeSort
SortedRowIterator.MutableMergeSort
TransformingRowIterator	A DelegatingRowIteratorthat transformseach returned Row.
UnmodifiableRowIterator
