Hi,
I'm having trouble getting the following code to work. Using
protoc.exe, I generated a file with the descriptor data using the --
descriptor_set_out file. I've written some Java code to read the
file, and try to instantiate a default instance of one of the objects
in the descriptor, so that

Hi all,
I'm trying to write a protobuf to detect the RSSI values of some
wireless stations in the area. I'm having some trouble 'updating' the
RSSI value of a station if it has already been seen before. At the
minute I'm doing a strcmp of the Station MAC from the message and the
MAC retrieved from
I was testing to see the upper limit for numbers of records in one
file.
I used the addressbook example, and I noticed that for one record
it generates file double the size.
for ex. size of the class I was putting into it was 48 bytes and the
file
was of 97 bytes on ubuntu 9.10.
Now, I go test it

You probably want stationlog.mutable_station(k);

Hope this helps,

If you're measuring using sizeof(), you won't account for memory allocated
by subobjects (strings and submessages are stored as pointers). You should
use Message::SpaceUsed() instead. The inmemory vs serialized size is going
to depend on your proto definition and how you use it. If you have a lot o
DescriptorProto.getDescriptorForType() returns the Descriptor for
DescriptorProto, not for the type which that DescriptorProto is describing.
Remember that DescriptorProto is just a protocol message like any other --
it does not have any special methods that recognize its higher-level
meaning.

Hi Jason,
Thanks for the quick reply.
I am not surprised by the increase in file size, But I am under impression
that If I insert the same record
thousand times, the size of file should be large accordingly,
e.g, assume that one record generates the file of size 32 bytes; with1024
records should
The most likely cause is a bug in your code where there's something you
aren't clearing each time you write a record, so at each iteration in your
loop, the record you're writing is getting bigger. Of course I can't say
for sure without seeing the code.

I am using add_person.cc provided in the sample file. The only change I have
done is,
a while loop around this code. So it's same record inserted multiple times.
// Write the new address book back to disk.fstream output(argv[1], ios::out
| ios::trunc | ios::binary);
*int nRecords = 10;*
*whil
That's not the right way to write multiple records. What you're doing is
writing multiple address books without proper boundaries between them. The
right thing to do would be to add multiple "person"s to one address book,
then write it once.
That said, the file produced by your code should grow
Kenton,
I did make some more progress today, along the lines of what you said
below. I'm seeing an issue where calling
DynamicMessage.getDefaultInstance(type) is not filling in the default
values. This is with 2.3.0 of GPB.
My proto file:
message StringTableEntry
{
required string lang = 1
"required" means "If this field is not explicitly set before build() is
called, or if parseFrom() parses a message missing this field, throw an
exception.". It does NOT mean "Automatically fill in this field.". Please
point me at any documentation which suggests the latter meaning so I can fix
it

Kenton,
This description in the MessageLite documentation is what led me to
believe the default values would be there. I figured I was
misinterpreting the documentation, or the meaning behind the default
value:
getDefaultInstanceForType
MessageLite getDefaultInstanceForType()
Get an instance of
Yeah, I can see how that is misleading (though it does not mention
"required" fields -- it claims all fields). It should say "Get an instance
of the type with no fields set. Because no fields are set, all getters for
singular fields will return default values and repeated fields will appear
empty
