Varint does an encoding whose length changes with the size of the
number - hence the name. So it can use between 1 and 10 bytes. So when
the value _events_written changes, re-writing the same number at the
beginning of the file will use a different number of bytes.
If you want to write a number th
Hi all,
I tried compiling protobuf with vs 2005 and vs 2008, the result is the
same:

http://code.google.com/apis/protocolbuffers/docs/proto.html#services describes
how to define services. However, protobuf does not provide an RPC
implementation. You may set the file option {lang}_generic_services = true
to have the protocol compiler generate a stub that can be used to integrate

Hi there,
Is it possible to define RPC methods in protobuf? From what I am
reading it seems that protobuf is only limited to data structured data
serializer. Is there any documentation I read about RPC methods in
protobuf if any is available?
Thank you for the assistance.
Kind regards,
Joshua.
I have an application where number of messages is a priory unknown. I can

Thanks Evan. Your response makes some things clear to me.
I meant to say I'd like chunks of 1MB ( I re-read my email and realize
it wasn't worded properly).
I now have some ideas that I'm going to try out.
Thanks again!

Thanks Evan
Seems like I am missing some files. I have just created a .proto file and
compiled it with protoc to get generated java files. I got .java file
compiled and put it with the java's source folder from protobuf 2.4.a in my
project folder.
But some of the class dependency of the files

You need to use the field descriptor for the field you want to look
at.
You can get ahold of the field descriptor by using "findFieldByName"
or "findFieldByNumber"
FieldDescriptor myFieldDescriptor =

Hi,
I was scanning the Language Guide and saw that there are simple ways
to access the MessageOptions defined in the java code like:
String value =
MyProtoFile.MyMessage.getDescriptor().getOptions().getExtension(MyProtoFile.myOption);
However if i have a field option like (using the e.g. in Lang
