                            {
        for (int i=0; i<Count(); i++) {
            if ((*this)[i] != NULL) {

    }

int IndexOf

Search for all occurrences

Finds the specified node in the array and returns its index.

Parameters:

node	- The node to find

Returns:

int - The index of the node in this array, or -1 if the node is not found

    {
        for (int i=0; i<Count(); i++) {
            if ((*this)[i] == node) {
                return i;
            }
        }
        return -1;
    }

bool Contains

(

INode *

node

)

[inline]

Search for all occurrences

Checks whether the specified node is in the array.

Parameters:

node	- The node to find

Returns:

bool - true if the node is in the array, otherwise false

    {
        return (IndexOf(node) >= 0);
    }

int AppendNode	(	INode *	node,
		bool	allowDups = false,
		int	allocExtra = 0
	)		[inline]

Search for all occurrences

Adds a node to the end of the array.

Parameters:

node	- The node to add to the array
allowDups	- If true, the specified node is added to the array without checking whether it's contained already in it. If false, the node is added to the array only if it doesn't exist in it yet.
allocExtra	- The number of extra items by which the array should be enlarged if all its items have been filled with nodes.

Returns:

- The number of nodes in the array prior to adding the specified node

                                                                            {
        if (!allowDups && Contains(node)) {
            return Count();
        }
        return Append(1, &node, allocExtra); 
    }

int InsertNode	(	INode *	node,
		int	at,
		bool	allowDups = false
	)		[inline]

Search for all occurrences

Inserts a node into the array at the specified position.

Parameters:

node	- The node to add to the array
at	- Array index where to insert the specified node. If a negative value is specified, the node will be appended to the array.
allowDups	- If true, the specified node is added to the array without checking whether it's contained already in it. If false, the node is added to the array only if it doesn't exist in it yet.

Returns:

- The array index at which the node was inserted, or -1 if the node was not inserted into the array

                                                                {
        if (at < 0) {
            AppendNode(node, allowDups);
            return Count();
        }
        else if (allowDups || !Contains(node)) {
            return Insert(at, 1, &node);
        }
        return -1;
    }
