CArray::InsertAt

  • 项目

voidInsertAt(intnIndex**,ARG_TYPEnewElement,intnCount=1);**
throw(CMemoryException);

voidInsertAt(intnStartIndex**,CArray*pNewArray);**
throw(CMemoryException);

Parameters

nIndex

An integer index that may be greater than the value returned by GetUpperBound.

ARG_TYPE

Template parameter specifying the type of elements in this array.

newElement

The element to be placed in this array.

nCount

The number of times this element should be inserted (defaults to 1).

nStartIndex

An integer index that may be greater than the value returned by GetUpperBound.

pNewArray

Another array that contains elements to be added to this array.

Remarks

The first version of InsertAt inserts one element (or multiple copies of an element) at a specified index in an array. In the process, it shifts up (by incrementing the index) the existing element at this index, and it shifts up all the elements above it.

The second version inserts all the elements from another CArray collection, starting at the nStartIndex position.

The SetAt function, in contrast, replaces one specified array element and does not shift any elements.

Example

// example for CArray::InsertAt

CArray<CPoint,CPoint> ptArray;

ptArray.Add(CPoint(10,20));   // Element 0
ptArray.Add(CPoint(30,40));   // Element 1 (will become element 2)
ptArray.InsertAt(1, CPoint(50,60));   // New element 1
