DataflowBlock::OutputAvailableAsync<TOutput> Method (ISourceBlock<TOutput>^)
Provides a Task<TResult> that asynchronously monitors the source for available output.
Assembly: System.Threading.Tasks.Dataflow (in System.Threading.Tasks.Dataflow.dll)
public: generic<typename TOutput> [ExtensionAttribute] static Task<bool>^ OutputAvailableAsync( ISourceBlock<TOutput>^ source )
Parameters
- source
-
Type:
System.Threading.Tasks.Dataflow::ISourceBlock<TOutput>^
The source to monitor.
Return Value
Type: System.Threading.Tasks::Task<Boolean>^A Task<TResult> that informs of whether and when more output is available. If, when the task completes, its Result is true, more output is available in the source (though another consumer of the source may retrieve the data).
If it returns false, more output is not and will never be available, due to the source completing prior to output being available.
Type Parameters
- TOutput
Specifies the type of data contained in the source.
