template<typename T>
| void hoa_utils::InsertionSort |
( |
std::vector< T > & |
swap_vec |
) |
|
Performs an insertion sort on a vector of elements.
- Parameters:
-
| swap_vec | The vector of elements to be sorted. |
Insertion sort should *only* be used for vectors that are already nearly sorted, or for vectors of size 10 or less. Otherwise this algorithm becomes computationally expensive and you should probably choose another sorting algorithm at that point. A good example of code that uses this algorithm well can be found in
map.cpp, which sorts map objects every frame. Because map objects change position slowly, there is usually no change or little relative change in sorting order from the previous pass.
- Note:
- The type of element that is passed should have its > and = operators functionally correct (if T is a class, you must overload these operators). In general, its good practice if you overload all comparison operators for these types.
Do not invoke this function with a vector of pointers to class-type objects, as it will cause a compilation error.
