2013-04-22 Thread Oliver Wang 
Can't you use ByteSize() method to get the size?

 Hi,

 I want to calculate the protocol buffer message size without reading the 
 stream to the end? I don't see the size of the outer most message is 
 stored. For example:

 message Person {
optional string name = 1; 
optional uint32 age = 2; 
 }

 There is no size store for the Person message if it is the outer most 
 message. Is that correct? If it is not where I can find it?

 Thanks,

 Son Nguyen

Not when you're parsing - you don't have a message instance yet!
