I have following classes
message StudentInfo {
required int32 id = 1;
required string name = 2;
required string class = 3;
optional string age = 4;
}
message StudentList{
repeated StudentInfo studentInfo = 1;
}
and i wrote StudentList Google Protocol buffer as given below
StudentList List;
for( int nIdx = 0; nIdx < 10; ++nIdx )
{
++m_nIndex;
string sIndex = NumberToString( m_nIndex);
string sName = "Name - " + sIndex;
StudentInfo* stuInfo = List.add_studentinfo();
stuInfo->set_id( nIdx );
stuInfo->set_age( sIndex);
stuInfo->set_class_( sIndex );
stuInfo->set_name( sName);
}
std::fstream output( "c:\\myData.bin" , ios::app |ios::out |
ios::binary );
if (!List.SerializeToOstream(&output))
{
//OutputDebugString( _T("Failed writing SPS"));
return;
}
output.close();
How to modify or delete a particular StudentInfo in this buffer??
