Class Summary
Class	Description
AbstractQuery<S extends Storable>	+ AbstractQuery implements a small set of common Query methods. +
AbstractQueryExecutor<S extends Storable>	+ AbstractQueryExecutor implements a small set of common QueryExecutor methods. +
CompositeScore<S extends Storable>	+ Evaluates an index for how well it matches a query's desired filtering and + ordering. +
DelegatedQueryExecutor<S extends Storable>	+ QueryExecutor which delegates by executing a Query on a Storage. +
DelegatedQueryExecutorFactory<S extends Storable>	+ QueryExecutorFactory which produces executors which delegate via `DelegatedQueryExecutor`. +
EmptyQuery<S extends Storable>	+ Special query implementation that fetches nothing. +
FilteredQueryExecutor<S extends Storable>	+ QueryExecutor which wraps another and filters results. +
FilteringScore<S extends Storable>	+ Evaluates an index for how well it matches a query's desired filtering. +
FullScanQueryExecutor<S extends Storable>	+ QueryExecutor which fully scans all Storables of a given type. +
IndexedQueryAnalyzer<S extends Storable>	+ Analyzes a simple query specification and determines which index is best + suited for its execution. +
IndexedQueryExecutor<S extends Storable>	+ QueryExecutor which utilizes an index. +
IterableQueryExecutor<S extends Storable>	+ QueryExecutor which fully scans an iterable collection. +
JoinedQueryExecutor<S extends Storable,T extends Storable>	+ QueryExecutor which joins a source and target executor, + producing results of target type. +
KeyQueryExecutor<S extends Storable>	+ QueryExecutor which has a fully specified key, and so cursors produce at + most one result. +
OrderingList<S extends Storable>	+ Produces unmodifiable lists of `orderings`. +
OrderingScore<S extends Storable>	+ Evaluates an index for how well it matches a query's desired ordering. +
QueryEngine<S extends Storable>	+ Complete rule-based query engine implementation. +
QueryExecutorCache<S extends Storable>	+ QueryExecutors should be cached since expensive analysis is often required to build + them. +
QueryHints	+ An immutable map of query hints. +
SortedQueryExecutor<S extends Storable>	+ QueryExecutor which wraps another and sorts the results. +
SortedQueryExecutor.ArraySortSupport<S extends Storable>
SortedQueryExecutor.MergeSortSupport<S extends Storable>
StandardQuery<S extends Storable>	+ Abstract query implementation which uses a `QueryExecutor`. +
StandardQueryFactory<S extends Storable>	+ Builds and caches StandardQuery instances. +
StorableIndexSet<S extends Storable>	+ Manages a set of `StorableIndex` objects, intended for reducing the + set such that the minimal amount of physical indexes need to be defined for + a specific type of `Storable`. +
UnionQueryAnalyzer<S extends Storable>	+ Analyzes a query specification and determines how it can be executed as a + union of smaller queries. +
UnionQueryExecutor<S extends Storable>	+ QueryExecutor which wraps several others and unions the results. +

Package com.amazon.carbonado.qe Description

Support for implementing a Query Engine. Repositories are free to use this + package to aid in their implementation, but user-level applications have no + need to use this package.
