Supports arrays of unsigned integers.
class CUIntArray : public CObject
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;
| Name | Description |
|---|---|
| CObArray::CObArray | Constructs an empty array. |
| Name | Description |
|---|---|
| CObArray::Add | Adds an element to the end of the array; grows the array if necessary. |
| CObArray::Append | Appends another array to the array; grows the array if necessary. |
| CObArray::Copy | Copies another array to the array; grows the array if necessary. |
| CObArray::ElementAt | Returns a temporary reference to the element pointer within the array. |
| CObArray::FreeExtra | Frees all unused memory above the current upper bound. |
| CObArray::GetAt | Returns the value at a given index. |
| CObArray::GetCount | Gets the number of elements in this array. |
| CObArray::GetData | Allows access to elements in the array. Can be NULL. |
| CObArray::GetSize | Gets the number of elements in this array. |
| CObArray::GetUpperBound | Returns the largest valid index. |
| CObArray::InsertAt | Inserts an element (or all the elements in another array) at a specified index. |
| CObArray::IsEmpty | Determines if the array is empty. |
| CObArray::RemoveAll | Removes all the elements from this array. |
| CObArray::RemoveAt | Removes an element at a specific index. |
| CObArray::SetAt | Sets the value for a given index; array not allowed to grow. |
| CObArray::SetAtGrow | Sets the value for a given index; grows the array if necessary. |
| CObArray::SetSize | Sets the number of elements to be contained in this array. |
| Name | Description |
|---|---|
| CObArray::operator [ ] | Sets or gets the element at the specified index. |
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. A UINT is the same size as a doubleword.
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.
