Member Function Documentation

void DisposeTemporary ( )

inline

Deletes all temporary nodes, such as those of type INodeTransformed, from the array.

See also

INodeTransformed

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

int IndexOf ( INode *  node )

inline

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

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

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

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;
    } 

bool RemoveNode ( INode *  n )

inline

Removes the supplied node from the array.

Parameters

n	Node to remove

Returns

true if the node was found and removed, false otherwise

    {
        int i = IndexOf(n);
        bool arrayContainsNode = (i >= 0);
        int arraySizeBeforeRemoval = Count();
        int arraySizeAfterRemoval = arraySizeBeforeRemoval;
        if (arrayContainsNode)
        {
            arraySizeAfterRemoval = Delete(i, 1);
        }
        DbgAssert(arraySizeAfterRemoval < arraySizeBeforeRemoval);
        return (arraySizeAfterRemoval < arraySizeBeforeRemoval);
    }
