CAtlList::SwapElements
Call this method to swap elements in the list.
void SwapElements(
POSITION pos1,
POSITION pos2
) throw( );
Parameters
pos1
The first POSITION value.pos2
The second POSITION value.
Remarks
Swaps the elements at the two positions specified. In debug builds, an assertion failure will occur if either position value is equal to NULL.
Example
// Define the integer list
CAtlList<int> myList;
// Populate the list
for (int i = 0; i < 100; i++)
{
myList.AddHead(i);
}
// Order is: 99, 98, 97, 96...
ATLASSERT(myList.GetHead() == 99);
ATLASSERT(myList.GetTail() == 0);
// Perform a crude bubble sort
for (int j = 0; j < 100; j++)
{
for(int i = 0; i < 99; i++)
{
if (myList.GetAt(myList.FindIndex(i)) >
myList.GetAt(myList.FindIndex(i+1)))
{
myList.SwapElements(myList.FindIndex(i), myList.FindIndex(i+1));
}
}
}
// Order is: 0, 1, 2, 3...
ATLASSERT(myList.GetHead() == 0);
ATLASSERT(myList.GetTail() == 99);
