inline

Remarks

Constructor. The list is initialed to NULL and the count is set to 0.

    {
        head = tail = NULL;
        count = 0;
    }

~LinkedListT ( )

inline

Member Function Documentation

void New ( )

inline

Remarks

The items in the list are deleted. The list is initialed to NULL and the count is set to 0.

    {
        while(head)
        {
            TE* next = (TE*)head->next;
            delete head;
            head = next;
        }
        head = tail = NULL;
        count = 0;
    }

int Count ( )

inline

Remarks

Returns the number of items in the list.

{ return count; }

void Append ( T &  item )

inline

Remarks

Adds a new item to the end of the list.

Parameters:

T& item

The item to add.

Operators:

    {
        TE* entry = new TE(item);
        if(tail)
            tail->next = entry;
        tail = entry;
        if(!head)
            head = entry;
        count++;
    }

T& operator[] ( int  index )

inline

Remarks

Allows access to items in the list using the array operator. The first item in the list has an index of 0.

Parameters:

int index

The array index of the item to access.

    {
        TE* e = head;
        while(index && e) {
            e = (TE*)e->next;
            index--;
        }
        // This should never happen, so we'll punt and return...
        // the head's data
        if(!e) {
            DbgAssert(0);
            return head->data;
        }
        return e->data;
    }

LinkedListT& operator= ( LinkedListT< T, TE > &  from )

inline

Remarks

Assignment operator.

Parameters:

LinkedListT &from

The list to copy.

Returns

A new linked list that is a copy of the list passed.

    {
        New();
        for(int i = 0; i < from.Count(); ++i)
            Append(from[i]);
        return *this;
    }
