Re: Using CopyingOutputStreamAdaptor and CodedOutputStream
No, that doesn't make sense.
I need to see the exact code, from the point where the CodedOutputStream is
constructed until it is destroyed.

Re: Using CopyingOutputStreamAdaptor and CodedOutputStream
Odd. By any chance, does this only happen when writing a zero-length
message?

Yes.
2. My new code looks like this:
MyStream myStream; // this implements CopyingOutputStream
CopyingOutputStreamAdaptor protoBufStream(&myStream);
CodedOutputStream codedOutputStream(&protoBufStream);
Then I write messages like this:
message.SerializeToCodedStream(&codedOutputStream);
When the CodedOutputStream's destructor gets called, my program
aborts
hard.. Looks like there is still 5192 bytes in its buffer, and I
think
I need to call Flush() on it, but there is no flush?
What is the error message? Stack trace?
thx

Using CopyingOutputStreamAdaptor and CodedOutputStream
Hi, I'm trying to use these to serialize messages to my own stream. I have a couple of questions: 1. If I use message.SerializeToCodedStream() do I still need to write the size of the message to the stream on my own first? Note, you can see the code I was previously using here: http://groups.google.com/group/protobuf/browse_thread/thread/9c9b410549e7eefd/b1268daa2e989c88?lnk=gst&q=streaming#b1268daa2e989c88 2. My new code looks like this: MyStream myStream; // this implements CopyingOutputStream CopyingOutputStreamAdaptor protoBufStream(&myStream); CodedOutputStream codedOutputStream(&protoBufStream); Then I write messages like this: message.SerializeToCodedStream(&codedOutputStream); When the CodedOutputStream's destructor gets called, my program aborts hard.. Looks like there is still 5192 bytes in its buffer, and I think I need to call Flush() on it, but there is no flush? thx - Alex --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Protocol Buffers" group.
