CObArray::Add

  • 项目

intAdd(CObject*newElement);
throw(CMemoryException);

Return Value

The index of the added element.

Parameters

newElement

The CObject pointer to be added to this array.

Remarks

Adds a new element to the end of an array, growing the array by 1. If SetSize has been used with an nGrowBy value greater than 1, then extra memory may be allocated. However, the upper bound will increase by only 1.

Example

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

// example for CObArray::Add

    CObArray array;
   
    array.Add( new CAge( 21 ) ); // Element 0
    array.Add( new CAge( 40 ) ); // Element 1
#ifdef _DEBUG
    afxDump.SetDepth( 1 );
    afxDump << "Add example: " << &array << "\n";
#endif

The results from this program are as follows:

Add example: A CObArray with 2 elements
    [0] = a CAge at $442A 21
    [1] = a CAge at $4468 40
