Interface Summary

Interface	Description
Enumerable<T>	Exposes the enumerator, which supports a simple iteration over a collection.
Enumerator<T>	Supports a simple iteration over a collection.
ExtendedEnumerable<TSource>	Extension methods in Enumerable.
ExtendedOrderedEnumerable<T>	Extension methods for OrderedEnumerable.
ExtendedOrderedQueryable<T>	Extension methods for OrderedQueryable.
Grouping<K,V>	Represents a collection of objects that have a common key.
Lookup<K,V>	Represents a collection of keys each mapped to one or more values.
OrderedEnumerable<T>	Represents the result of applying a sorting operation to an Enumerable.
OrderedQueryable<T>	Represents the result of applying a sorting operation to a Queryable.
Queryable<T>	Provides functionality to evaluate queries against a specific data source wherein the type of the data is known.
QueryableDefaults.Replayable<T>	Replayable.
QueryableFactory<T>	Factory for building Queryable objects.
QueryProvider	Defines methods to create and execute queries that are described by a Queryable object.
RawEnumerable<T>	Exposes the enumerator, which supports a simple iteration over a collection, without the extension methods.
RawQueryable<T>	Core methods that define a Queryable.

Class Summary

Class	Description
AbstractEnumerable<T>	Abstract implementation of the Enumerable interface that implements the extension methods.
AbstractEnumerable2<T>	Abstract implementation of the Enumerable interface that implements the extension methods.
AbstractQueryable<T>	Abstract implementation of the Queryable interface that implements the extension methods.
BaseQueryable<TSource>	Skeleton implementation of Queryable.
CartesianProductEnumerator<T,E>	Enumerator over the cartesian product of enumerators.
DefaultEnumerable<T>	Implementation of the Enumerable interface that implements the extension methods by calling into the Extensions class.
DelegatingEnumerator<T>	Simple enumerator that just delegates all calls to the passed enumerator.
EnumerableDefaults	Default implementations of methods in the Enumerable interface.
Extensions	Contains what, in LINQ.NET, would be extension methods.
Linq4j	Utility and factory methods for Linq4j.
MemoryEnumerable<E>	Enumerable that has a (limited) memory for n past and m future steps.
MemoryEnumerator<E>	Enumerator that keeps some recent and some "future" values.
MemoryFactory<E>	Contains the State and changes internally.
MemoryFactory.Memory<E>	Contents of a "memory segment", used for implementing the MATCH_RECOGNIZE operator.
Ord<E>	Pair of an element and an ordinal.
QueryableDefaults	Default implementations for methods in the Queryable interface.
QueryableDefaults.NonLeafReplayableQueryable<T>	Non-leaf replayable queryable.
QueryableDefaults.ReplayableQueryable<T>	Replayable queryable.
QueryableRecorder<T>	Implementation of QueryableFactory that records each event and returns an object that can replay the event when you call its QueryableDefaults.ReplayableQueryable.replay(QueryableFactory) method.
QueryProviderImpl	Partial implementation of QueryProvider.
QueryProviderImpl.QueryableImpl<T>	Binds an expression to this query provider.
TransformedEnumerator<F,E>	Enumerator that applies a transform to each value from a backing enumerator.

Enum Summary

Enum	Description
JoinType	Enumeration of join types.
OpType	Operator type.

Annotation Types Summary

Annotation Type	Description
PackageMarker	This is a dummy annotation that forces javac to produce output for otherwise empty package-info.java.
