# ACE\_DNode(3)

Implementation element in a bilinked list.

## NAME

ACE\_DNode -  Implementation element in a bilinked list.

## SYNOPSIS

```
#include <ace/Containers.h>
template<class T>
class ACE_DNode
{
  public:
    friend class ACE_Ordered_MultiSet<T>;
    friend class ACE_Ordered_MultiSet_Iterator<T>;
    ~ACE_DNode (void);
  private:
    ACE_DNode (const T &i, ACE_DNode<T> *n = 0, ACE_DNode<T> *p = 0);
    ACE_DNode<T> *next_;
    ACE_DNode<T> *prev_;
    T item_;
};
```

## DESCRIPTION

This implementation of an unordered set uses a fixed array. This implementation does not allow duplicates...

## Initialization methods

```
ACE_DNode (const T &i, ACE_DNode<T> *n = 0, ACE_DNode<T> *p = 0);
```

```
ACE_DNode<T> *next_;
```

Pointer to next element in the list of ACE\_DNodes.

```
ACE_DNode<T> *prev_;
```

Pointer to previous element in the list of ACE\_DNodes.

```
T item_;
```

Current value of the item in this node.
