Detailed Description
template<class W, class R>
class grpc_impl::ServerReaderWriter< W, R >
Synchronous (blocking) server-side API for a bidirectional streaming call, where the incoming message stream coming from the client has messages of type R, and the outgoing message streaming coming from the server has messages of type W.
Member Function Documentation
◆ NextMessageSize()
|
inlineoverridevirtual |
Get an upper bound on the next message size available for reading on this stream.
Implements grpc_impl::internal::ReaderInterface< R >.
◆ Read()
|
inlineoverridevirtual |
Block to read a message and parse to msg.
Returns true on success. This is thread-safe with respect to Write or \WritesDone methods on the same stream. It should not be called concurrently with another Read on the same stream as the order of delivery will not be defined.
- Parameters
-
[out] msg The read message.
- Returns
- false when there will be no more incoming messages, either because the other side has called WritesDone() or the stream has failed (or been cancelled).
Implements grpc_impl::internal::ReaderInterface< R >.
◆ SendInitialMetadata()
|
inlineoverridevirtual |
See the ServerStreamingInterface.SendInitialMetadata method for semantics.
Note that initial metadata will be affected by the ServerContext associated with this call.
Implements grpc_impl::internal::ServerStreamingInterface.
◆ Write()
|
inlineoverridevirtual |
Block to write msg to the stream with WriteOptions options.
This is thread-safe with respect to ReaderInterface::Read
- Parameters
-
msg The message to be written to the stream. options The WriteOptions affecting the write operation.
- Returns
- true on success, false when the stream has been closed.
Implements grpc_impl::internal::WriterInterface< W >.
