The abstract interface to sorted array indexes.

Sorted array indexes are used for sequential enumeration of nodes in sorted arrays.

Every sorted array index has the internal current node pointer. The current node pointer points to the first node in the array when the sorted array index is created. The current node is set to NULL if the array is empty.

CSortedArrayIndex

CSortedArrayIndex();

Constructs the sorted array index.

~CSortedArrayIndex

virtual ~CSortedArrayIndex();

Destroys the sorted array index.

GetNode

virtual XNode GetNode() = 0;

Returns the current node of this sorted array index.

Returns:

the current node of this sorted array index, or NULL if node enumeration had reached the end of the sorted array

Iterate

virtual void Iterate() = 0;

Moves the current node pointer to the next node in the sorted array.

The current node is set to NULL if node enumeration had reached the end of the sorted array.
