Definition

Called by a linked ITargetBlock<TInput> to release a previously reserved DataflowMessageHeader by this ISourceBlock<TOutput>.

 virtual void System.Threading.Tasks.Dataflow.ISourceBlock<TOutput>.ReleaseReservation(System::Threading::Tasks::Dataflow::DataflowMessageHeader messageHeader, System::Threading::Tasks::Dataflow::ITargetBlock<TOutput> ^ target) = System::Threading::Tasks::Dataflow::ISourceBlock<TOutput>::ReleaseReservation;
void ISourceBlock<TOutput>.ReleaseReservation (System.Threading.Tasks.Dataflow.DataflowMessageHeader messageHeader, System.Threading.Tasks.Dataflow.ITargetBlock<TOutput> target);
Sub ReleaseReservation (messageHeader As DataflowMessageHeader, target As ITargetBlock(Of TOutput)) Implements ISourceBlock(Of TOutput).ReleaseReservation

Parameters

messageHeader
DataflowMessageHeader DataflowMessageHeader DataflowMessageHeader

The DataflowMessageHeader of the reserved message being released.

target
ITargetBlock<TOutput>

The ITargetBlock<TInput> releasing the message it previously reserved.

Implements

Exceptions

The messageHeader is not valid.

The target did not have the message reserved.

Remarks

Only ITargetBlock<TInput> instances linked to this ISourceBlock<TOutput> instance may use ReleaseReservation, and it must only be used to release DataflowMessageHeader instances previously and successfully reserved by the target.
