Hi,
I am wondering about the best way of forwarding received protocol
buffer messages from one entity to another without having to parse the
entire message just to serialize it again.
My scenario is the following: I have a process A connected to process
B using local IPC. B is in turn connected
Hi there,
I recently started working with Protocol Buffers. I used the
Addressbook Example to become acquainted with the PBs. (http://
code.google.com/intl/de-DE/apis/protocolbuffers/docs/
javatutorial.html)
The only difference is that I use an OutputStream to write the address
book instance (in
Thanks a lot Kenton. I went for the second option. If you are storing
a lot of data in pb format, wrapping around with an outer message
makes you parse all at once. it is like DOM vs SAX for XML I guess.
thanks again!

This whole topic - how to save multiple messages to a single stream -
comes up frequently enough that I'm starting to think there should be
a more flexible answer than what's in the FAQ. Declaring a one-byte

The value returned by Message::ByteSize() does not match the actually
number of bytes that are consumed after writing a message to a
stream. Example:
some_message m;
/* ... populate m ... */
size_t len = m.ByteSize();
int pos =
Here you go...attached is an example that fails quite reliably (for me).
Compile like so:
mkdir build
cd build
cmake ../
make
./test-pb

This example is too big for me to debug. Can't you reproduce this with a
10-line program + proto file?

Oops, had some bad math in that last sample. This is more correct (but
still fails).
