C++ (Cpp) Array2D::getColData Examples

Example #1

void GridPerimToArray(const Array2D<U> &grid, std::vector<U> &vec){
  assert(vec.size()==0); //Ensure receiving array is empty

  std::vector<U> vec2copy;

  vec2copy = grid.getRowData(0);                         //Top
  vec.insert(vec.end(),vec2copy.begin(),vec2copy.end());

  vec2copy = grid.getColData(grid.width()-1);        //Right
  vec.insert(vec.end(),vec2copy.begin()+1,vec2copy.end());
  
  vec2copy = grid.getRowData(grid.height()-1);       //Bottom
  vec.insert(vec.end(),vec2copy.begin(),vec2copy.end()-1);
  
  vec2copy = grid.getColData(0);                         //Left
  vec.insert(vec.end(),vec2copy.begin()+1,vec2copy.end()-1);
