Reading std::vector <std::vector <TVector3> > --- please help

[alex460]

Hello,

Can anybody PLEASE help me? I want to read each element of a std::vector <std::vector <TVector3> > obj1;

Here is what I am doing;

for(int i=0; i<obj1.size(); i++){
for(std::vector<TVector3>::iterator itr = obj1[i].begin(); itr =obj1[i].end(); ++itr){
(*itr).Print();
}
std::cout << "*******" << std::endl;
}

When I do above I get the error message as follows;

error: could not convert ‘(itr <unknown operator> ((const __gnu_cxx::__normal_iterator<TVector3*, std::vector<TVector3> >&)((const __gnu_cxx::__normal_iterator<TVector3*, std::vector<TVector3> >*)(&((std::vector<TVector3>*)vertexcand_vec.std::vector<_Tp, _Alloc>::operator[] [with _Tp = std::vector<TVector3>, _Alloc = std::allocator<std::vector<TVector3> >, std::vector<_Tp, _Alloc>::reference = std::vector<TVector3>&, std::vector::size_type = long unsigned int](((long unsigned int)i)))->std::vector<_Tp, _Alloc>::end [with _Tp = TVector3, _Alloc = std::allocator<TVector3>, std::vector<_Tp, _Alloc>::iterator = __gnu_cxx::__normal_iterator<TVector3*, std::vector<TVector3> >, typename std::vector<_Tp, _Alloc>::_Base::_Tp_alloc_type::pointer = TVector3*]()))))’ to ‘bool’


Please help. Thank You.

Are you trying to pack one vector inside of another? I guess I don't understand what a "TVector3" data type is. Link?

This

itr =obj1[i].end();

should be

itr != obj1[i].end();

Oh, so it was a typo in my code, Sorry I could not see it. It works when I replaced itr =obj1[i].end();

with

itr != obj1[i].end();

Thanks.

Just notice that, unreadable as they may seem, template error messages sometimes can be read. The above message says "could not convert foo to bool" if you ignore the messy part. Then you just have to look for boolean expressions.
