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:

• T* T::next () const;
• void T::next (T *);
• T* T::prev () const;
• void T::prev (T* );

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.

(

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>

(

ACE_Intrusive_List< T > &

rhs

)

[inline]

Swap two lists.

template<class T >

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
