I am new to GPB and a bit new to ruby, but the project I am working on
requires ruby.
I have successful installed the protocol_buffer gem and successfully
generated a test file with 10 GPB messages in it. I have verified with a
hex editor that all 10 messages are in the file.
Now I want to read the messages back in and process them. Regardless of how
I try to read the message file, I always only get the last message. I have
tried several different ways and I am stuck.
Here is the last snippet and yes I know it's a infinite loop, but at this
point it doesn't matter. I still only get the last message.
Could someone point me to a example of how to read the messages 1 at time
until there are no more messages? if not in ruby, then in python.
Code:
require 'protobuf/message/message'
require 'protobuf/message/enum'
require 'protobuf/message/service'
require 'protobuf/message/extend'
module Test
class Interface < ::Protobuf::Message
defined_in __FILE__
required :string, :name, 1
end
class System < ::Protobuf::Message
defined_in __FILE__
required :string, :name, 1
end
class Rec < ::Protobuf::Message
defined_in __FILE__
optional :uint32, :timestamp, 1
optional :System, :system, 2
repeated :Interface, :interface, 3
end
end
jrec = Test::Rec.new
counter = 1
file = File.open("testdata", "r")
while (jrec.parse_from_file(file))
puts "#{jrec.system.name}: #{counter}"
counter = counter + 1
end
file.close
When I do a jrec.display it also only shows the last message from the file.
