Sort a vector of custom objects / sort a vector of pointers
Sort objects:
struct taxpayersCmp{
bool operator()(const taxpayer &a,const taxpayer &b) const{
return a.Float<b.Float;
}
} taxpayersCmp_;
//...
std::sort(taxpayers.begin(),taxpayers.end(),taxpayersCmp_);
This tip is from http://www.cplusplus.com/forum/general/5885/ . Sort objects whose pointers are stored in a vector:
static struct nodeCmp {
bool operator()(const shared_ptr<Node>& a, const shared_ptr<Node>& b) const {
return a->getValue() < b->getValue();
}
} nodeCmp_;
//...
std::sort( vec.begin(), vec.end(), nodeCmp_ );
