hello:
we defined two object in field.proto
message Record{
optional int id = 1;
}
message RecordSet{
repeated Record record= 1;
}
so when we define a Record pointer,we do like this:
RecordSet recordsetA,recordsetB;
Recrod *pRecordA = recordsetA.add_record();
pRecordA->set_id(111);
actually ,recordsetB has the same member as fieldsetA,we can only do
like this:
Record *pRecordB = recordsetB.add_record();
pRecordB->CopyFrom(*pRecordA);
we found that it cost much time to copy.
if there is this method,we can solve this problem:
recordasetB.add_record(pRecordA);
in this way ,we don't need to copy。
i've read topic in this forum, add_record() this api just for thread
safe and don't worry about the pRecordA being accidently changed。
so hope for your answer.
thans!!
