JoinBlock<T1,T2> Class

Definition

Provides a dataflow block that joins across multiple dataflow sources, not necessarily of the same type, waiting for one item to arrive for each type before they’re all released together as a tuple consisting of one item per type.

public sealed class JoinBlock<T1,T2> : System.Threading.Tasks.Dataflow.IReceivableSourceBlock<Tuple<T1,T2>>, System.Threading.Tasks.Dataflow.ISourceBlock<Tuple<T1,T2>>
Type Parameters
T1

Specifies the type of data accepted by the block's first target.

T2

Specifies the type of data accepted by the block's second target.

Remarks

Note

The TPL Dataflow Library (System.Threading.Tasks.Dataflow namespace) is not distributed with the .NET Framework 4.5. To install the N:System.Threading.Tasks.Dataflow namespace, open your project in Visual Studio 2012, choose Manage NuGet Packages from the Project menu, and search online for the Microsoft.Tpl.Dataflow package.

Constructors

JoinBlock<T1,T2>()

Initializes a new JoinBlock<T1,T2>.

JoinBlock<T1,T2>(GroupingDataflowBlockOptions)

Initializes a new JoinBlock<T1,T2>.

Properties

Completion

Gets a Task that represents the asynchronous operation and completion of the dataflow block.

OutputCount

Gets the number of output items available to be received from this block.

Target1

Gets a target that may be used to offer messages of the first type.

Target2

Gets a target that may be used to offer messages of the second type.

Methods

Complete()

Signals to the IDataflowBlock that it should not accept nor produce any more messages nor consume any more postponed messages.

LinkTo(ITargetBlock<Tuple<T1,T2>>, DataflowLinkOptions)

Links the ISourceBlock<TOutput> to the specified ITargetBlock<TInput> .

ToString()

Returns a string that represents the formatted name of this IDataflowBlock instance.

TryReceive(Predicate<Tuple<T1,T2>>, Tuple<T1,T2>)

Attempts to synchronously receive an available output item from the IReceivableSourceBlock<TOutput>.

TryReceiveAll(IList<Tuple<T1,T2>>)

Attempts to synchronously receive all available items from the IReceivableSourceBlock<TOutput>.

Explicit Interface Implementations

IDataflowBlock.Fault(Exception)

Causes the IDataflowBlock to complete in a Faulted state.

ISourceBlock<Tuple<T1,T2>>.ConsumeMessage(DataflowMessageHeader, ITargetBlock<Tuple<T1,T2>>, Boolean)
ISourceBlock<Tuple<T1,T2>>.ReleaseReservation(DataflowMessageHeader, ITargetBlock<Tuple<T1,T2>>)
ISourceBlock<Tuple<T1,T2>>.ReserveMessage(DataflowMessageHeader, ITargetBlock<Tuple<T1,T2>>)
