A convenient substitute for the SetAt member function.
VALUE& operator[](
   ARG_KEY key 
);
Parameters
- VALUE 
 Template parameter specifying the type of the map value.
- ARG_KEY 
 Template parameter specifying the type of the key value.
- key 
 The key used to retrieve the value from the map.
Remarks
Thus it can be used only on the left side of an assignment statement (an l-value). If there is no map element with the specified key, then a new element is created.
There is no "right side" (r-value) equivalent to this operator because there is a possibility that a key may not be found in the map. Use the Lookup member function for element retrieval.
Example
See the example for CMap::Lookup.
