class Packet{public:Packet(string fTime, string rID) : filingTime(fTime), recordID(rID)  string getFilingTime() {return filingTime;}  string getRecordId() {return recordID;}private:  string filingTime;  string recordID;};

Two options to be able to use :

1. Define an operator== method for Packet and change the vector<Packet*> to vector<Packet>.

   bool Packet::operator==(const Packet& rhs) const{    if (getFilingTime() != rhs.getFilingTime())        return false;    if (getSpid() != rhs.getSpid())        return false;    return true;}//etc.int main(){    vector
         
           pkts;    pkts.push_back(Packet("10:20", "1004"));    pkts.push_back(Packet("10:20", "1004")); // not unique (duplicate of the line above)    pkts.push_back(Packet("10:20", "251"));    pkts.push_back(Packet("10:20", "1006"));    // remove packet from vector if time and ID are the same     pkts.erase(unique(pkts.begin(), pkts.end()), pkts.end());                       return 0;}
         

2. Keep the vector as vector<Packet*> and define a method to compare the elements.

   bool comparePacketPtrs(Packet* lhs, Packet* rhs){    if (lhs->getFilingTime() != rhs->getFilingTime())        return false;    if (lhs->getSpid() != rhs->getSpid())        return false;    return true;}//etc.int main(){    vector
         
           pkts;    pkts.push_back(new Packet("10:20", "1004"));    pkts.push_back(new Packet("10:20", "1004")); // not unique (duplicate of the line above)    pkts.push_back(new Packet("10:20", "251"));    pkts.push_back(new Packet("10:20", "1006"));    // remove packet from vector if time and ID are the same     pkts.erase(unique(pkts.begin(), pkts.end(), comparePacketPtrs), pkts.end());                       return 0;}
