Hmm... that strikes me as strange. I understand that the Message

they would work more along the lines of String and StringBuilder,

The best way to think of it is:
Builder : Java Message :: C++ Message : const C++ Message
As far as performance goes, it is a common mistake to confuse C/C++
heap memory allocation costs to Java heap allocation. In the common
case, allocations in Java are just a few instructions... comperable
Hi,
I haven't actually used the Java protobuf API, but it seems to me from
the quick occasional glance that this isn't entirely true. I mean,
specifically in response to the code snippet posted in the original
message, I would possibly:
1. Reuse the Builder object by calling its clear() method.

Hi Kenton,
Thanks for your reply.
You can't continue to use a Builder after calling build(). Even if we made
it so you could, it would be building an entirely new object, not reusing
the old one. We can't make it reuse the old one because that would break
the immutability guarantee of

No. Sorry. This just doesn't fit at all with the Java

My code looks like:

while ( !stream.isAtEnd() )
