class grpc::ServerSplitStreamer&lt; RequestType, ResponseType &gt;</h3>
<p>A class to represent a flow-controlled server-side streaming call. </p>
<p>This is something of a hybrid between server-side and bidi streaming. This is invoked through a server-side streaming call on the client side, but the server responds to it as though it were a bidi streaming call that must first have exactly 1 Read and then any number of Writes. </p>
