JoinBlock<T1,T2,T3>
Class
Definition
Provides a dataflow block that joins across multiple dataflow sources, which are not necessarily of the same type, waiting for one item to arrive for each type before they’re all released together as a tuple that contains one item per type.
public sealed class JoinBlock<T1,T2,T3> : System.Threading.Tasks.Dataflow.IReceivableSourceBlock<Tuple<T1,T2,T3>>, System.Threading.Tasks.Dataflow.ISourceBlock<Tuple<T1,T2,T3>>
- 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.
- T3
Specifies the type of data accepted by the block's third target.

Note
The TPL Dataflow Library (System.Threading.Tasks.Dataflow namespace) is not distributed with the .NET Framework 4.5. To install the 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,T3>() |
Initializes a new JoinBlock<T1,T2,T3>. |
| JoinBlock<T1,T2,T3>(GroupingDataflowBlockOptions) |
Initializes a new JoinBlock<T1,T2,T3>. |
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. |
| Target3 |
Gets a target that may be used to offer messages of the third 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,T3>>, DataflowLinkOptions) |
Links the source block to the specified target block. |
| ToString() |
Returns a string that represents the formatted name of this IDataflowBlock instance. |
| TryReceive(Predicate<Tuple<T1,T2,T3>>, Tuple<T1,T2,T3>) |
Attempts to synchronously receive an available output item from the IReceivableSourceBlock<TOutput>. |
| TryReceiveAll(IList<Tuple<T1,T2,T3>>) |
Attempts to synchronously receive all available items from the IReceivableSourceBlock<TOutput>. |
