Methods
| LinkTo(IQueryResultReceiver<TResult>) |
Link the query step to a block to process the result. The query engine will call it exactly once before using this query step. (Inherited from IQueryDataProducer<TResult>) |
| OnRequestProcessFinishedAsync(IQueryProcessRequest) |
The query step tells the receiver that it finished all processing for one request. (Inherited from IQueryResultReceiver<TResult>) |
| ReceiveResultAsync(QueryProcessResult<TResult>) |
Receives one piece of the result from a query step. A single request can produce multiple data, and it is expected this method will be called multiple times during the process. (Inherited from IQueryResultReceiver<TResult>) |
