Type Parameters

TEntity

The type of items in the query result.

Implements: IAsyncQueryable IEnumerable<T> IEnumerable<TEntity> IReadOnlyCollection<TEntity> IEnumerable

Methods

QueryAsync(CancellationToken)	Starts a query and receive results asynchronously. Note: the result can only be accessed once, and cannot be reset.
QueryAsync(ICommonQueryableSpace, CancellationToken)	Starts a query and receive results asynchronously. Note: the result can only be accessed once, and cannot be reset.
SubscribeAsync(ICommonQueryableSpace, IObserver<IQueryResults<TEntity>>, CancellationToken)	Subscribes results from a query, which automatically reruns when data source is changed.
SubscribeAsync(ICommonQueryableSpace, IObserver<IQueryResults<TEntity>>)	Subscribes results from a query, which automatically reruns when data source is changed.
SubscribeAsync(IObserver<IQueryResults<TEntity>>, CancellationToken)	Subscribes results from a query, which automatically reruns when data source is changed.
SubscribeAsync(IObserver<IQueryResults<TEntity>>)	Subscribes results from a query, which automatically reruns when data source is changed.
TrackUpdatesAsync(IObserver<IQueryTrackUpdates<TEntity>>, CancellationToken)	Tracks a query, which automatically reruns when the data source is changed.

Extension Methods

AsUpdatable<TEntity>(IAsyncQueryable<TEntity>)	Initialize an update action.
Get<TSource,TResult>(IAsyncQueryable<TSource>, Expression<Func<TSource,IAsyncQueryable<TResult>>>)	Gets a child collection to be returned from the query.
Skip<TEntity>(IAsyncQueryable<TEntity>, Int32)	Bypasses a specified number of elements in a query and returns the remaining elements.
Take<TEntity>(IAsyncQueryable<TEntity>, Int32)	Returns a specified number of elements from the query.
Where<TEntity>(IAsyncQueryable<TEntity>, Expression<Func<TEntity,Boolean>>)	Filters a sequence of values based on a predicate.
With<TEntity>(IAsyncQueryable<TEntity>, Expression<Func<TEntity,IAsyncQueryable>>, Boolean)	Obsolete. Include a child collection in the query result.
With<TEntity>(IAsyncQueryable<TEntity>, Expression<Func<TEntity,IAsyncQueryable>>)	Include a child collection in the query result.
With<TEntity>(IAsyncQueryable<TEntity>, Expression<Func<TEntity,Object>>)	Include a specific property in the query result.
WithRequired<TEntity>(IAsyncQueryable<TEntity>, Expression<Func<TEntity,IAsyncQueryable>>)	Include a non-empty child collection in the query result.
EmptyIfNull<T>(IEnumerable<T>)	Return this enumeration in case it is not null. In case it is null return empty enumeration.
