Called by a linked ITargetBlock<TInput> to release a previously reserved DataflowMessageHeader by this ISourceBlock<TOutput>.
virtual void System.Threading.Tasks.Dataflow.ISourceBlock<T>.ReleaseReservation(System::Threading::Tasks::Dataflow::DataflowMessageHeader messageHeader, System::Threading::Tasks::Dataflow::ITargetBlock<T> ^ target) = System::Threading::Tasks::Dataflow::ISourceBlock<T>::ReleaseReservation;
void ISourceBlock<T>.ReleaseReservation (System.Threading.Tasks.Dataflow.DataflowMessageHeader messageHeader, System.Threading.Tasks.Dataflow.ITargetBlock<T> target);
abstract member System.Threading.Tasks.Dataflow.ISourceBlock<T>.ReleaseReservation : System.Threading.Tasks.Dataflow.DataflowMessageHeader * System.Threading.Tasks.Dataflow.ITargetBlock<'T> -> unit

Sub ReleaseReservation (messageHeader As DataflowMessageHeader, target As ITargetBlock(Of T)) Implements ISourceBlock(Of T).ReleaseReservation
- messageHeader
- DataflowMessageHeader
The DataflowMessageHeader of the reserved message being released.
- target
- ITargetBlock<T>
The ITargetBlock<TInput> releasing the message it previously reserved.
The messageHeader
is not valid.
The target
is null
.
The target
did not have the message reserved.
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.
