Member Function Documentation

NextMessageSize()

template<class R >

virtual bool grpc::internal::ReaderInterface< R >::NextMessageSize ( uint32_t *  sz )

pure virtual

Get an upper bound on the next message size available for reading on this stream.

Implemented in grpc::ServerSplitStreamer< RequestType, ResponseType >, grpc::ServerUnaryStreamer< RequestType, ResponseType >, and grpc::ServerReaderWriter< W, R >.

Read()

template<class R >

virtual bool grpc::internal::ReaderInterface< R >::Read ( R *  msg )

pure virtual

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).

Implemented in grpc::ServerSplitStreamer< RequestType, ResponseType >, grpc::ServerUnaryStreamer< RequestType, ResponseType >, and grpc::ServerReaderWriter< W, R >.
