CUIntArray Class

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 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.
