Question

I have a vector of vector of my object and I get a pointer of this vector. My problem is I can’t create an iterator with that.
This my code :

vector<vector<AbstractBlock*>> *vectorMap = _level->getMap()->getVectorMap();

for(vector<AbstractBlock*>::iterator i = vectorMap[colonneX-1].begin(); i < vectorMap[colonneX-1].end(); i++)
{
    /*some operations*/
}

It failed on vectorMap[colonneX-1].begin(), if the vectorMap is not a pointer I can do this

How I can make this?

Thanks!

Dereference vectorMap:

for(vector<AbstractBlock*>::iterator i = (*vectorMap)[colonneX-1].begin();
    i != (*vectorMap)[colonneX-1].end(); i++)
