CMap::SetAt

voidSetAt(ARG_KEYkey,ARG_VALUEnewValue);

Parameters

ARG_KEY

Template parameter specifying the type of the key parameter.

key

Specifies the key of the new element.

ARG_VALUE

Template parameter specifying the type of the newValue parameter.

newValue

Specifies the value of the new element.

Remarks

The primary means to insert an element in a map. First, the key is looked up. If the key is found, then the corresponding value is changed; otherwise a new key-value pair is created.

Example

CMap<int,int,CPoint,CPoint> myMap;

   // Add 10 elements to the map.
   for (int i=0;i < 10;i++)
      myMap.SetAt( i, CPoint(i, i) );

   // Remove the elements with even key values.
   POSITION pos = myMap.GetStartPosition();
   int    nKey;
   CPoint pt;
   while (pos != NULL)
   {
      myMap.GetNextAssoc( pos, nKey, pt );

      if ((nKey%2) == 0)
         myMap.RemoveKey( nKey );
   }

    afxDump.SetDepth( 1 );
    afxDump << "myMap: " << &myMap << "\n";
