# ACE\_DLList(3)

A double-linked list container class.

## NAME

ACE\_DLList -  A double-linked list container class.

## SYNOPSIS

```
#include <ace/Containers.h>
template<class T>
class ACE_DLList : public ACE_DLList_Base
{
  public:
    friend class ACE_DLList_Node;
    friend class ACE_Double_Linked_List_Iterator<T>;
    friend class ACE_DLList_Iterator<T>;
    friend class ACE_DLList_Reverse_Iterator<T>;
    void operator= (ACE_DLList<T> &l);
    T *insert_tail (T *new_item);
    T *insert_head (T *new_item);
    T *delete_head (void);
    T *delete_tail (void);
    int get (T *&item, size_t slot = 0);
    void dump (void) const;
    int remove (ACE_DLList_Node *n);
    ACE_DLList (ACE_Allocator *alloc = 0);
    ACE_DLList (ACE_DLList<T> &l);
    ~ACE_DLList (void);
};
```

## DESCRIPTION

This implementation uses ACE\_Double\_Linked\_List to perform the logic behind this container class.  It delegates all of its calls to ACE\_Double\_Linked\_List.

## Classic queue operations.

```
T *insert_tail (T *new_item);
```

Delegates to ACE\_Double\_Linked\_List.

```
T *insert_head (T *new_item);
```

Delegates to ACE\_Double\_Linked\_List.

```
T *delete_head (void);
```

Delegates to ACE\_Double\_Linked\_List.

```
T *delete_tail (void);
```

Delegates to ACE\_Double\_Linked\_List.

## Additional utility methods.

```
int get (T *&item, size_t slot = 0);
```

Delegates to ACE\_Double\_Linked\_List, but where ACE\_Double\_Linked\_List returns the node as the item, this get returns the contents of the node in item.

```
void dump (void) const;
```

Delegates to ACE\_Double\_Linked\_List.

```
int remove (ACE_DLList_Node *n);
```

Delegates to ACE\_Double\_Linked\_List.

## Initialization and termination methods.

```
ACE_DLList (ACE_Allocator *alloc = 0);
```

Delegates to ACE\_Double\_Linked\_List.

```
ACE_DLList (ACE_DLList<T> &l);
```

Delegates to ACE\_Double\_Linked\_List.

```
~ACE_DLList (void);
```

Deletes the list starting from the head.
