Detailed Description

template<class T>
class ACE_Intrusive_List< T >

Implement an intrusive double linked list.

Intrusive lists assume that the elements they contain the pointers required to build the list. They are useful as light-weight containers and free-lists.

The template argument T must implement the following methods:

A simple way to satisfy the Intrusive_List requirements would be to implement a helper class:

class My_Object : public ACE_Intrusive_List_Node<My_Object> {
....
};

typedef ACE_Intrusive_List<My_Object> My_Object_List;

However, ACE is supported on platforms that would surely get confused using such templates.

Todo:
The ACE_Message_Queue is an example of an intrusive list (or queue) but it is not implemented in terms of this class.

Member Function Documentation

template<class T>
ACE_INLINE int ACE_Intrusive_List< T >::empty void   )  const
 

Returns 1 if the container is empty, otherwise returns 0.

template<class T>
ACE_INLINE T * ACE_Intrusive_List< T >::head void   )  const
 

Get the element at the head of the queue.

template<class T>
ACE_Intrusive_List<T>& ACE_Intrusive_List< T >::operator= const ACE_Intrusive_List< T > &   )  [private]
 

template<class T>
T * ACE_Intrusive_List< T >::pop_back void   ) 
 

Remove the element at the end of the list.

template<class T>
T * ACE_Intrusive_List< T >::pop_front void   ) 
 

Remove the element at the beginning of the list.

template<class T>
void ACE_Intrusive_List< T >::push_back T *  node  ) 
 

Insert an element at the end of the list.

template<class T>
void ACE_Intrusive_List< T >::push_front T *  node  ) 
 

Insert an element at the beginning of the list.

template<class T>
void ACE_Intrusive_List< T >::remove T *  node  ) 
 

Remove a element from the list.

Verify that the element is still in the list before removing it.

template<class T>
void ACE_Intrusive_List< T >::remove_i T *  node  )  [private]
 

Remove a element from the list.

No attempts are performed to check if T* really belongs to the list. The effects of removing an invalid element are unspecified

template<class T>
ACE_INLINE T * ACE_Intrusive_List< T >::tail void   )  const
 

Get the element at the tail of the queue.
