DataflowBlock Class

.NET Framework 4.5

Provides a set of static (Shared in Visual Basic) methods for working with dataflow blocks.

System.Object
  System.Threading.Tasks.Dataflow.DataflowBlock

Namespace:  System.Threading.Tasks.Dataflow
Assembly:  System.Threading.Tasks.Dataflow (in System.Threading.Tasks.Dataflow.dll)
public static class DataflowBlock

The DataflowBlock type exposes the following members.

  NameDescription
Public methodStatic memberSupported by Portable Class LibraryAsObservable<TOutput>Creates a new IObservable<T> abstraction over the ISourceBlock<TOutput>.
Public methodStatic memberSupported by Portable Class LibraryAsObserver<TInput>Creates a new IObserver<T> abstraction over the ITargetBlock<TInput>.
Public methodStatic memberSupported by Portable Class LibraryChoose<T1, T2>(ISourceBlock<T1>, Action<T1>, ISourceBlock<T2>, Action<T2>)Monitors two dataflow sources, invoking the provided handler for whichever source makes data available first.
Public methodStatic memberSupported by Portable Class LibraryChoose<T1, T2>(ISourceBlock<T1>, Action<T1>, ISourceBlock<T2>, Action<T2>, DataflowBlockOptions)Monitors two dataflow sources, invoking the provided handler for whichever source makes data available first.
Public methodStatic memberSupported by Portable Class LibraryChoose<T1, T2, T3>(ISourceBlock<T1>, Action<T1>, ISourceBlock<T2>, Action<T2>, ISourceBlock<T3>, Action<T3>)Monitors three dataflow sources, invoking the provided handler for whichever source makes data available first.
Public methodStatic memberSupported by Portable Class LibraryChoose<T1, T2, T3>(ISourceBlock<T1>, Action<T1>, ISourceBlock<T2>, Action<T2>, ISourceBlock<T3>, Action<T3>, DataflowBlockOptions)Monitors three dataflow sources, invoking the provided handler for whichever source makes data available first.
Public methodStatic memberSupported by Portable Class LibraryEncapsulate<TInput, TOutput>Encapsulates a target and a source into a single propagator.
Public methodStatic memberSupported by Portable Class LibraryLinkTo<TOutput>(ISourceBlock<TOutput>, ITargetBlock<TOutput>)Links the ISourceBlock<TOutput> to the specified ITargetBlock<TInput>.
Public methodStatic memberSupported by Portable Class LibraryLinkTo<TOutput>(ISourceBlock<TOutput>, ITargetBlock<TOutput>, Predicate<TOutput>)Links the ISourceBlock<TOutput> to the specified ITargetBlock<TInput> using the specified filter.
Public methodStatic memberSupported by Portable Class LibraryLinkTo<TOutput>(ISourceBlock<TOutput>, ITargetBlock<TOutput>, DataflowLinkOptions, Predicate<TOutput>)Links the ISourceBlock<TOutput> to the specified ITargetBlock<TInput> using the specified filter.
Public methodStatic memberSupported by Portable Class LibraryNullTarget<TInput>Gets a target block that synchronously accepts all messages offered to it and drops them.
Public methodStatic memberSupported by Portable Class LibraryOutputAvailableAsync<TOutput>(ISourceBlock<TOutput>)Provides a Task<TResult> that asynchronously monitors the source for available output.
Public methodStatic memberSupported by Portable Class LibraryOutputAvailableAsync<TOutput>(ISourceBlock<TOutput>, CancellationToken)Provides a Task<TResult> that asynchronously monitors the source for available output.
Public methodStatic memberSupported by Portable Class LibraryPost<TInput>Posts an item to the ITargetBlock<TInput>.
Public methodStatic memberSupported by Portable Class LibraryReceive<TOutput>(ISourceBlock<TOutput>)Synchronously receives a value from a specified source.
Public methodStatic memberSupported by Portable Class LibraryReceive<TOutput>(ISourceBlock<TOutput>, CancellationToken)Synchronously receives a value from a specified source and provides a token to cancel the operation.
Public methodStatic memberSupported by Portable Class LibraryReceive<TOutput>(ISourceBlock<TOutput>, TimeSpan)Synchronously receives a value from a specified source, observing an optional time-out period.
Public methodStatic memberSupported by Portable Class LibraryReceive<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.
Public methodStatic memberSupported by Portable Class LibraryReceiveAsync<TOutput>(ISourceBlock<TOutput>)Asynchronously receives a value from a specified source.
Public methodStatic memberSupported by Portable Class LibraryReceiveAsync<TOutput>(ISourceBlock<TOutput>, CancellationToken)Asynchronously receives a value from a specified source and provides a token to cancel the operation.
Public methodStatic memberSupported by Portable Class LibraryReceiveAsync<TOutput>(ISourceBlock<TOutput>, TimeSpan)Asynchronously receives a value from a specified source, observing an optional time-out period.
Public methodStatic memberSupported by Portable Class LibraryReceiveAsync<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.
Public methodStatic memberSupported by Portable Class LibrarySendAsync<TInput>(ITargetBlock<TInput>, TInput)Asynchronously offers a message to the target message block, allowing for postponement.
Public methodStatic memberSupported by Portable Class LibrarySendAsync<TInput>(ITargetBlock<TInput>, TInput, CancellationToken)Asynchronously offers a message to the target message block, allowing for postponement.
Public methodStatic memberSupported by Portable Class LibraryTryReceive<TOutput>Attempts to synchronously receive an item from the ISourceBlock<TOutput>.
