CAtlList::FindIndex

  • Articolo

Call this method to obtain the position of an element, given an index value.

POSITION FindIndex( 
   size_t iElement  
) const throw( );

Parameters

  • iElement
    The zero-based index of the required list element.

Return Value

Returns the corresponding POSITION value, or NULL if iElement is out of range.

Remarks

This method returns the POSITION corresponding to a given index value, allowing access to the nth element in the list.

In debug builds, an assertion failure will occur if the list object is not valid.

Example

// Define the integer list
CAtlList<int> myList;

// Populate the list 
for (int i = 0; i < 100; i++)
{
   myList.AddTail(i);
}

// Iterate through the entire list 
for (size_t j = 0; j < myList.GetCount(); j++)
{
   size_t i = myList.GetAt(myList.FindIndex(j));
   ATLASSERT(i == j);
}
