initializing a vector of custom class in c++
- by Flamewires
Hey basically Im trying to store a "solution" and create a vector of these. The problem I'm having is with initialization. Heres my class for reference
class Solution
{
private:
// boost::thread m_Thread;
int itt_found;
int dim;
pfn_fitness f;
double value;
std::vector<double> x;
public:
Solution(size_t size, int funcNo) : itt_found(0), x(size, 0.0), value(0.0), dim(30), f(Eval_Functions[funcNo])
{
for (int i = 1; i < (int) size; i++) {
x[i] = ((double)rand()/((double)RAND_MAX))*maxs[funcNo];
}
}
Solution() : itt_found(0), x(31, 0.0), value(0.0), dim(30), f(Eval_Functions[1])
{
for (int i = 1; i < 31; i++) {
x[i] = ((double)rand()/((double)RAND_MAX))*maxs[1];
}
}
Solution operator= (Solution S)
{
x = S.GetX();
itt_found = S.GetIttFound();
dim = S.GetDim();
f = S.GetFunc();
value = S.GetValue();
return *this;
}
void start()
{
value = f (dim, x);
}
/* plus additional getter/setter methods*/
}
Solution S(30, 1) or Solution(2, 5) work and initalizes everything, but I need X of these solution objects. std::vector<Solution> Parents(X) will create X solutions with the default constructor and i want to construct using the (int, int) constructor. Is there any easy(one liner?) way to do this? Or would i have to do something like:
size_t numparents = 10;
vector<Solution> Parents;
Parents.reserve(numparents);
for (int i = 0; i<(int)numparents; i++) {
Solution S(31, 0);
Parents.push_back(S);
}
