Method Detail

bind

public abstract void bind(io.grpc.Metadata metadata)

This method is called before the interceptCall(ServerCall, Metadata, ServerCallHandler) call happens and allows extracting data from the metadata to the vert.x context.

Parameters:

metadata - the grpc connection context

interceptCall

public <ReqT,RespT> io.grpc.ServerCall.Listener<ReqT> interceptCall(io.grpc.ServerCall<ReqT,RespT> call,
                                                                    io.grpc.Metadata metadata,
                                                                    io.grpc.ServerCallHandler<ReqT,RespT> handler)

Specified by:

interceptCall in interface io.grpc.ServerInterceptor

get
