Detailed Description

template<typename Request, typename Response>
class ugrpc::server::InputStream< Request, Response >

Controls a request stream -> single response RPC.

This class is not thread-safe except for GetContext.

The RPC is cancelled on destruction unless the stream has been finished.

If any method throws, further methods must not be called on the same stream, except for GetContext.

InputStream()

template<typename Request , typename Response >

ugrpc::server::InputStream< Request, Response >::InputStream	(	impl::CallParams &&	call_params,
		impl::RawReader< Request, Response > &	stream
	)

For internal use only.

Member Function Documentation

Finish()

template<typename Request , typename Response >

void ugrpc::server::InputStream< Request, Response >::Finish

(

const Response &

response

)

Complete the RPC successfully.

Finish must not be called multiple times for the same RPC.

Parameters

response

the single Response to send to the client

Exceptions

ugrpc::server::RpcError

on an RPC error

Definition at line 348 of file rpc.hpp.

FinishWithError()

template<typename Request , typename Response >

void ugrpc::server::InputStream< Request, Response >::FinishWithError ( const grpc::Status &  status )

overridevirtual

Complete the RPC with an error.

Finish must not be called multiple times for the same RPC.

Parameters

status

error details

Exceptions

ugrpc::server::RpcError

on an RPC error

Implements ugrpc::server::CallAnyBase.

Definition at line 359 of file rpc.hpp.

IsFinished()

template<typename Request , typename Response >

bool ugrpc::server::InputStream< Request, Response >::IsFinished ( ) const

overridevirtual

Implements ugrpc::server::CallAnyBase.

Definition at line 372 of file rpc.hpp.

Read()

template<typename Request , typename Response >

bool ugrpc::server::InputStream< Request, Response >::Read

(

Request &

request

)

Await and read the next incoming message.

Parameters

request

where to put the request on success

Returns

true on success, false on end-of-input
