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.

Constructor & Destructor Documentation

template<class T >
ACE_Intrusive_List< T >::ACE_Intrusive_List ( void  )

Constructor. Use user specified allocation strategy if specified.

template<class T >
ACE_Intrusive_List< T >::~ACE_Intrusive_List ( void  )

Destructor.

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

Member Function Documentation

template<class T >
T * ACE_Intrusive_List< T >::head ( void  ) const [inline]

Get the element at the head of the queue.

template<class T >
bool ACE_Intrusive_List< T >::is_empty ( void  ) const [inline]

Returns true if the container is empty, otherwise returns false.

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 >::swap ( ACE_Intrusive_List< T > &  rhs) [inline]

Swap two lists.

template<class T >
T * ACE_Intrusive_List< T >::tail ( void  ) const [inline]

Get the element at the tail of the queue.

template<class T>
void ACE_Intrusive_List< T >::unsafe_remove ( T *  node)

Remove a element from the list without checking.

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