CObArray::SetAtGrow

Sets the array element at the specified index.

void SetAtGrow(
   INT_PTR nIndex,
   CObject* newElement 
);

Parameters

  • nIndex
    An integer index that is greater than or equal to 0.

  • newElement
    The object pointer to be added to this array. A NULL value is allowed.

Remarks

The array grows automatically if necessary (that is, the upper bound is adjusted to accommodate the new element).

Example

See CObList::CObList for a listing of the CAge class used in all collection examples.

CObArray arr;

arr.Add(new CAge(21)); // Element 0
arr.Add(new CAge(40)); // Element 1
arr.SetAtGrow(3, new CAge(65)); // Element 2 deliberately
                                      // skipped.
#ifdef _DEBUG
   afxDump.SetDepth(1);
   afxDump << _T("SetAtGrow example: ") << &arr << _T("\n");
#endif      

The results from this program are as follows:

SetAtGrow example: A CObArray with 4 elements

[0] = a CAge at $47C0 21

[1] = a CAge at $4800 40

[2] = NULL

[3] = a CAge at $4840 65
