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
override this.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

Parameters

messageHeader: DataflowMessageHeader

The DataflowMessageHeader of the reserved message being released.

target: ITargetBlock<T>

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

Implements

ReleaseReservation(DataflowMessageHeader, ITargetBlock<TOutput>)

Exceptions

ArgumentException

The messageHeader is not valid.

ArgumentNullException

The target is null.

InvalidOperationException

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.
