Detailed Description
template<class W, class R>
class grpc_impl::ServerAsyncReader< W, R >
Async server-side API for doing client-streaming RPCs, where the incoming message stream from the client has messages of type R, and the single response message sent from the server is type W.

See the ServerAsyncReaderInterface.Read method for semantics.
Side effect:
- also sends initial metadata if not alreay sent.
- uses the ServerContext associated with this call to send possible initial and trailing metadata.
Note: msg is not sent if status has a non-OK code.
gRPC doesn't take ownership or a reference to msg and status, so it is safe to deallocate once Finish returns.
Implements grpc_impl::ServerAsyncReaderInterface< W, R >.

Implements grpc_impl::ServerAsyncReaderInterface< W, R >.
◆ Read()
|
inlineoverridevirtual |
Read a message of type R into msg.
Completion will be notified by tag on the associated completion queue. This is thread-safe with respect to Write or WritesDone methods. It should not be called concurrently with other streaming APIs on the same stream. It is not meaningful to call it concurrently with another AsyncReaderInterface::Read on the same stream since reads on the same stream are delivered in order.
- Parameters
-
[out] msg Where to eventually store the read message. [in] tag The tag identifying the operation.
Side effect: note that this method attempt to receive initial metadata for a stream if it hasn't yet been received.
Implements grpc_impl::internal::AsyncReaderInterface< R >.
◆ SendInitialMetadata()
|
inlineoverridevirtual |
See ServerAsyncStreamingInterface::SendInitialMetadata for semantics.
Implicit input parameter:
- The initial metadata that will be sent to the client from this op will be taken from the ServerContext associated with the call.
Implements grpc::internal::ServerAsyncStreamingInterface.
