In grpc, what is the generated_pool method doing? -


i'm bit confused of autogenerated code in grpc , can't find documentation it.

here's proto file called route_guide.proto

syntax = "proto3";  ... package routeguide;  // interface exported server. service routeguide {   // simple rpc.   //   // obtains feature @ given position.   //   // feature empty name returned if there's no feature @ given   // position.   rpc getfeature(point) returns (feature) {}  ... // points represented latitude-longitude pairs in e7 representation // (degrees multiplied 10**7 , rounded nearest integer). // latitudes should in range +/- 90 degrees , longitude should in // range +/- 180 degrees (inclusive). message point {   int32 latitude = 1;   int32 longitude = 2; }  // latitude-longitude rectangle, represented 2 diagonally opposite  ...  // feature names @ given point. // // if feature not named, name empty. message feature {   // name of feature.   string name = 1;    // point feature detected.   point location = 2; }

if run code, 

protoc -i ../../protos --ruby_out=../lib --grpc_out=../lib --plugin=protoc-gen-grpc=`which grpc_ruby_plugin` ../../protos/route_guide.proto

it auto gens code:

# generated protocol buffer compiler.  not edit! # source: route_guide.proto  require 'google/protobuf'  google::protobuf::descriptorpool.generated_pool.build   add_message "routeguide.point"     optional :latitude, :int32, 1     optional :longitude, :int32, 2   end   add_message "routeguide.rectangle"     optional :lo, :message, 1, "routeguide.point"     optional :hi, :message, 2, "routeguide.point"   end   add_message "routeguide.feature"     optional :name, :string, 1     optional :location, :message, 2, "routeguide.point"   end   add_message "routeguide.routenote"     optional :location, :message, 1, "routeguide.point"     optional :message, :string, 2   end   add_message "routeguide.routesummary"     optional :point_count, :int32, 1     optional :feature_count, :int32, 2     optional :distance, :int32, 3     optional :elapsed_time, :int32, 4   end end  module routeguide   point = google::protobuf::descriptorpool.generated_pool.lookup("routeguide.point").msgclass   rectangle = google::protobuf::descriptorpool.generated_pool.lookup("routeguide.rectangle").msgclass   feature = google::protobuf::descriptorpool.generated_pool.lookup("routeguide.feature").msgclass   routenote = google::protobuf::descriptorpool.generated_pool.lookup("routeguide.routenote").msgclass   routesummary = google::protobuf::descriptorpool.generated_pool.lookup("routeguide.routesummary").msgclass end

what these descriptorpool classes? purpose of class?what file do?

i'm curious line:

google::protobuf::descriptorpool.generated_pool.lookup("routeguide.point").msgclass
