CUIntArray Class

class CUIntArray : public CObject


The CUIntArray class supports arrays of unsigned integers. An unsigned integer, or UINT, differs from words and doublewords in that the physical size of a UINT can change depending on the target operating environment. Under Windows version 3.1, a UINT is the same size as a WORD. Under Windows NT and Windows 95/98, a UINT is the same size as a doubleword.

The member functions of CUIntArray are similar to the member functions of class CObArray. Because of this similarity, you can use the CObArray reference documentation for member function specifics. Wherever you see a CObject pointer as a function parameter or return value, substitute a UINT.

CObject* CObArray::GetAt( int <nIndex> ) const;

for example, translates to

UINT CUIntArray::GetAt( int <nIndex> ) const;

CUIntArray incorporates the IMPLEMENT_DYNAMIC macro to support run-time type access and dumping to a CDumpContext object. If you need a dump of individual unsigned integer elements, you must set the depth of the dump context to 1 or greater. Unsigned integer arrays cannot be serialized.

Note   Before using an array, use SetSize to establish its size and allocate memory for it. If you do not use SetSize, adding elements to your array causes it to be frequently reallocated and copied. Frequent reallocation and copying are inefficient and can fragment memory.

For more information on using CUIntArray, see the article Collections.
