Interface RawQueryable<T>

Type Parameters:

T - Element type

All Superinterfaces:

Enumerable<T>, ExtendedEnumerable<T>, Iterable<T>, RawEnumerable<T>

All Known Subinterfaces:

ExtendedOrderedQueryable<T>, OrderedQueryable<T>, Queryable<T>, QueryableDefaults.Replayable<T>

All Known Implementing Classes:

AbstractQueryable, BaseQueryable, QueryableDefaults.NonLeafReplayableQueryable, QueryableDefaults.ReplayableQueryable, QueryProviderImpl.QueryableImpl

public interface RawQueryable<T>
extends Enumerable<T>

Core methods that define a Queryable.

The other methods in Queryable, defined in ExtendedQueryable, can easily be implemented by calling the corresponding static methods in Extensions.
