Re: [protobuf] Search inside a protocolbuffers file
We only have auto-generated API docs. http://code.google.com/apis/protocolbuffers/docs/reference/cpp/index.html BTW, to implement such a database, you can actually build it using protobuf APIs. Probably don't need to dig into protobuf implementations.

Probably don't need to dig into protobuf implementations. Thank you Pherl. I will go through the apidocs. The reason why I thought the file-format should be known is because, the search will be faster that way. I can go through all the records (?) in the protocol buffer file iteratively using the APIs but I believe that will be slower. I was wondering if I could implement a cursor based API which will return matching record for a passed query, one at a time, until there are no more matches, etc. Sankar On Tue, Apr 19, 2011 at 7:28 PM, Sankar P sankar.curios...@gmail.com wrote: On Thu, Apr 7, 2011 at 8:07 PM, Sankar P sankar.curios...@gmail.com wrote: On Thu, Apr 7, 2011 at 3:06 PM, Pherl Liu liuj...@google.com wrote: protobuf officially does not provide this function.

Re: [protobuf] Search inside a protocolbuffers file
protobuf officially does not provide this function. There might be some 3rd party libraries though.
