Uses of QueryExecutor in com.amazon.carbonado.qe

Classes in com.amazon.carbonado.qe that implement QueryExecutor

Modifier and Type	Class and Description
class	AbstractQueryExecutor<S extends Storable> AbstractQueryExecutor implements a small set of common QueryExecutor methods.
class	DelegatedQueryExecutor<S extends Storable> QueryExecutor which delegates by executing a Query on a Storage.
class	FilteredQueryExecutor<S extends Storable> QueryExecutor which wraps another and filters results.
class	FullScanQueryExecutor<S extends Storable> QueryExecutor which fully scans all Storables of a given type.
class	IndexedQueryExecutor<S extends Storable> QueryExecutor which utilizes an index.
class	IterableQueryExecutor<S extends Storable> QueryExecutor which fully scans an iterable collection.
class	JoinedQueryExecutor<S extends Storable,T extends Storable> QueryExecutor which joins a source and target executor, producing results of target type.
class	KeyQueryExecutor<S extends Storable> QueryExecutor which has a fully specified key, and so cursors produce at most one result.
class	SortedQueryExecutor<S extends Storable> QueryExecutor which wraps another and sorts the results.
class	UnionQueryExecutor<S extends Storable> QueryExecutor which wraps several others and unions the results.
