List Public Interface (cont.)

• Locating places on the list

Iterator Begin  () const;  // return iterator at first element
Iterator End    () const;  // return iterator past the end
Iterator rBegin () const;  // return iterator at last element
Iterator rEnd   () const;  // return iterator before the beginning

• Accessing values on the list

T& Front ();  // return reference to element at front of list
T& Back  ();  // return reference to element at back of list

• Non-member operators

bool operator ==      (const TList<T>& L1, const TList<T>& L2);
bool operator !=      (const TList<T>& L1, const TList<T>& L2);
ostream& operator << (ostream& os, const TList<T>& L);
