◆ NextMessageSize()

◆ Read()

template<class R>

Block to read a message and parse to msg.

Returns true on success. This is thread-safe with respect to Write or 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]msgThe 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).

Implemented in grpc_impl::ServerSplitStreamer< RequestType, ResponseType >, grpc_impl::ServerUnaryStreamer< RequestType, ResponseType >, grpc_impl::ServerReaderWriter< W, R >, grpc_impl::ServerReader< R >, grpc_impl::ClientReaderWriter< W, R >, and grpc_impl::ClientReader< R >.
