Server-side is actually a bigger pain than client-side, but also the server-side-style approach won't work on client-side.
ClientCall<ReqT, RespT> interceptCall(
MethodDescriptor<ReqT, RespT> method, CallOptions callOptions, Channel
next) {
MethodDescriptor isMethod = method.toBuilder()
.setRequestMarshaller(myInputStreamMarshaller)
.setResponseMarshaller(myInputStreamMarshaller)
.build();
ClientCall<InputStream, InputStream> cc = next.newCall(isMethod,
callOptions);
// wrap the call to your liking.
// do things like method.streamRequest(req) to convert between messages
and bytes
}
The MyInputStreamMarshaller itself is trivial; use InputStream as the type
T and just return the argument to each method.
