ISourceBlock<TOutput> Interface

Definition

Namespace:

System.Threading.Tasks.Dataflow

Assembly:

System.Threading.Tasks.Dataflow.dll

Represents a dataflow block that is a source of data.

generic <typename TOutput>
public interface class ISourceBlock : System::Threading::Tasks::Dataflow::IDataflowBlock

public interface ISourceBlock<out TOutput> : System.Threading.Tasks.Dataflow.IDataflowBlock

type ISourceBlock<'Output> = interface
    interface IDataflowBlock

Public Interface ISourceBlock(Of Out TOutput)
Implements IDataflowBlock

Type Parameters

TOutput

Specifies the type of data supplied by the ISourceBlock<TOutput>.

This type parameter is covariant. That is, you can use either the type you specified or any type that is more derived. For more information about covariance and contravariance, see Covariance and Contravariance in Generics.

Remarks

Note

The TPL Dataflow Library (the System.Threading.Tasks.Dataflow namespace) is not distributed with .NET. To install the System.Threading.Tasks.Dataflow namespace in Visual Studio, open your project, choose Manage NuGet Packages from the Project menu, and search online for the System.Threading.Tasks.Dataflow package. Alternatively, to install it using the .NET Core CLI, run dotnet add package System.Threading.Tasks.Dataflow.

Properties

Completion

Gets a Task that represents the asynchronous operation and completion of the dataflow block. (Inherited from IDataflowBlock)

Methods

Complete()	Signals to the IDataflowBlock that it should not accept nor produce any more messages nor consume any more postponed messages. (Inherited from IDataflowBlock)
ConsumeMessage(DataflowMessageHeader, ITargetBlock<TOutput>, Boolean)	Called by a linked ITargetBlock<TInput> to accept and consume a DataflowMessageHeader previously offered by this ISourceBlock<TOutput>.
Fault(Exception)	Causes the IDataflowBlock to complete in a Faulted state. (Inherited from IDataflowBlock)
LinkTo(ITargetBlock<TOutput>, DataflowLinkOptions)	Links the ISourceBlock<TOutput> to the specified ITargetBlock<TInput>.
ReleaseReservation(DataflowMessageHeader, ITargetBlock<TOutput>)	Called by a linked ITargetBlock<TInput> to release a previously reserved DataflowMessageHeader by this ISourceBlock<TOutput>.
ReserveMessage(DataflowMessageHeader, ITargetBlock<TOutput>)	Called by a linked ITargetBlock<TInput> to reserve a previously offered DataflowMessageHeader by this ISourceBlock<TOutput>.

Extension Methods

AsObservable<TOutput>(ISourceBlock<TOutput>)	Creates a new IObservable<T> abstraction over the ISourceBlock<TOutput>.
LinkTo<TOutput>(ISourceBlock<TOutput>, ITargetBlock<TOutput>, Predicate<TOutput>)	Links the ISourceBlock<TOutput> to the specified ITargetBlock<TInput> using the specified filter.
LinkTo<TOutput>(ISourceBlock<TOutput>, ITargetBlock<TOutput>, DataflowLinkOptions, Predicate<TOutput>)	Links the ISourceBlock<TOutput> to the specified ITargetBlock<TInput> using the specified filter.
LinkTo<TOutput>(ISourceBlock<TOutput>, ITargetBlock<TOutput>)	Links the ISourceBlock<TOutput> to the specified ITargetBlock<TInput>.
OutputAvailableAsync<TOutput>(ISourceBlock<TOutput>, CancellationToken)	Provides a Task<TResult> that asynchronously monitors the source for available output.
OutputAvailableAsync<TOutput>(ISourceBlock<TOutput>)	Provides a Task<TResult> that asynchronously monitors the source for available output.
Receive<TOutput>(ISourceBlock<TOutput>, CancellationToken)	Synchronously receives a value from a specified source and provides a token to cancel the operation.
Receive<TOutput>(ISourceBlock<TOutput>, TimeSpan, CancellationToken)	Synchronously receives a value from a specified source, providing a token to cancel the operation and observing an optional time-out interval.
Receive<TOutput>(ISourceBlock<TOutput>, TimeSpan)	Synchronously receives a value from a specified source, observing an optional time-out period.
Receive<TOutput>(ISourceBlock<TOutput>)	Synchronously receives a value from a specified source.
ReceiveAsync<TOutput>(ISourceBlock<TOutput>, CancellationToken)	Asynchronously receives a value from a specified source and provides a token to cancel the operation.
ReceiveAsync<TOutput>(ISourceBlock<TOutput>, TimeSpan, CancellationToken)	Asynchronously receives a value from a specified source, providing a token to cancel the operation and observing an optional time-out interval.
