## PUBLIC MEMBERS

    friend class ACE_TPQ_Iterator;

    ACE_Token_Proxy_Queue (void);

Construction.

    ~ACE_Token_Proxy_Queue (void);

Destructor

    void enqueue (ACE_TPQ_Entry* new_entry, int position);

Enqueue a proxy, nesting level, client_id, and a magic cookie at the given position in the list. If the position is -1, we enqueue at the end of the list (I think).

    const ACE_TPQ_Entry* head (void);

Top of the queue.

    void dequeue (void);

Remove the top waiter.

    void remove (const ACE_TPQ_Entry *remove_me);

Remove the waiter whose proxy ref matches remove_me.

    int size (void);

The number of waiters.

    void dump (void) const;

Dump the state of the class.

## PROTECTED MEMBERS

    ACE_TPQ_Entry *head_;

    ACE_TPQ_Entry *tail_;

Tail.

    int size_;

Size.
